I almost roll my eyes whenever i hear someone say "... i don't know what to get for them..." Because if anyone wants to get someone a present, they should at least know this person enough to know what this person would want or would like to have. Some people love dvds, or a cd or chocolates or flowers or fancy a pack of assorted pattern paper or nail polish such as glitter or a certain color or black or a hat or a scarf or anything!!! If you know the person at all you will know exactly what the person wants or would like. end rant
Give her a mouthful... of your firm love. (no innuendo intended) Just get her a really nice stuffed bear. A really nice (and sentimental) bear would be around $30 or $40. You might even find one that can be dressed in miniature clothes. Very cute. Very... brotherly...
umm.. A emo boi? JK! I would get her something... reasonable.. like a new car.. oh.. uhh.. no, get her a perfume.. girls love that I hear.
Be careful with perfume unless you buy one that she already has and likes, or has told you she wants. It's a very individual thing and the same one can smell different on different women.
