LoL ... I know I'm probs answering a little late, but I didn't do anything for my bro, and he turned 16. But if your that kind of sister ... then get him something that he'll like and cherish for ages to come :)
Give him a hug! That's what I do for my brother every year
hit him in the head and you should be good
:O! Give him money, or buy him a nice present- Something that you know he likes ;D
Get him a violent video game. That should work.
I have no clue!
My brother also turned 15 but I didn't get him anything, I don't like him! (at all!!!!)
Well, make a card for him. Now the gift depends to his character and ehat things he likes. Maybe a video game or a CD. If he likes movies then get him a DVD but the best would be a suprise party! Ok, I think the most important is make him a card and write your feelings -if they're good! If not then forget it-
Uuummm... make him a favor booklet! like i'll wash the dishes or clean your room or do the laundry instead of you!
Make him a card or buy him anything he likes depends on how he is does he have a favourite musician or band you could get him a poster/shirt or just give him money
get him a porn movie!! :D hahahaha....nahh i'm sure if he is 15 already has a whole bunch downloaded so it won't be much of a present! :) um...........................................
GET HIM A UNICORN!!! .....(a pink one!)
