Are a great deal of elder siblings close to this?

My 14 year old son is getting into lots of bad stuff like ditching university, bad grades, i think he's drinking alcohol, etc..
but whenever my 11 year old daughter wants something like advice, help beside homework, when they hang out he buys her stuff like food and smoothies, and more.
why is he doing bad stuff but acting resembling the perfect older brother it doesn't make sense to me.

idk if this is the right category
might want to closely examine his friends if he is virtuous at home and not at school it may be peer pressure... or if not problems with playful at school some kids act out so that they can be deemed as cool and relieve some of the coy..if you haven't already ask him.. then go to the school mee tthe parents of his friends.. after that you can analyze the info and find the source..
Bad influences, friends he's around next to and probably something that kids around his age do, let him realize that whats he is doing its not gonna take him anywhere and let your daughter address to him if you feel like he won't listen to you. If you say that he act really nice with his sister like an older brother should perform with his sis or bro, then let her do the conversation, probably he'll realize his little sister is looking up to him and make him change his ways.
Answers:    This sounds a bit close to my 17 year old daughter. Although she receives high results in school, she is into drugs, alcohol and smoking - no matter what I do, she won't stop. However, around the house and near her little brother (quite a bit younger, he's three years old) she's an angel. It's as though she is two separate people; she loves her family and school and helping, however she also loves partying. She's the epitome of a privileged popular, party-girl in wealthy suburbia and I can assure you I didn't bring her up that way.

The guidance I've received on here is that this is just a phase and will pass. I think you could do a short time snooping, since your son is not at the stage of craziness that my daughter is at. There's still hope! l.o.l. but really...check his phone and swallow the mommy-guilt. See what you can and then try to have an open address with him about what he's been up to.
Well, I don't know if a lot of elder siblings are like that, but I am. I don't things as bad as cutting university (my grades are good) and drinking, but I get into trouble a lot. But when I'm with my sister (I'm 15, she's 12), that change. I buy her a game or a video every time we go out together (if I have the money) and I'll backing her with whatever. Basically, if my sister needs me, I'm within.

I don't why I act like this. I just do.
Well start monitoring you son more. If he has a phone and set book ask the company to send you what he texts with your subsequent bill. You might need to be more mean to your son, tell him he cant do anything till he have finished his homework or study for 20mins. Start to threatin him tell him if he grades dont get up he will have no life span. Make him pee in a cup after you think he has be drinking it will show up in his piss.

He is nice to his sister because brother and sister are usually close no matter what.
Peer Pressure.

If he doesn't do these things at arts school his friends probably mock him about being a "wuss" (more like ahh you're for a moment b**ch scared of your mommy/daddy). Of course he doesn't want to be mocked/bullied so he does what others do to fit in.

My little brother is like this too.
deeply of kids do that kind of stuff, my older sister ditched school and get bad grades for a little while. It's just a phase and it will usually overrun.
And the reason he does all those things for his little sister is probably because he's just her elder brother and every older brother wants to protect their little sister and be there for her.
wow, he sounds resembling an awesome big brother , and it doesnt make sense, not with him acting out like that. I regard as there is something bothering him, is there any abuse contained by the household? the only reason I ask is because growing up my older siblings took thoroughness of me, but that was because my father was abusive and they sheltered me from the knock about. But they acted out, no one in my family graduate school and we all got into drugs, disappointingly. We are different now, but still. Maybe you should just sit him down and point blank ask him, it wont hurt to ask. good luck.

You may not own abused him but someone else may have. Ask him what is bothering him and maybe he will open up.
