What to get for them?

I would pick out a budget for both of them and have it be equal amounts of money. If you pick like say 30$ each, you can get two very different things for each girl that will still be of the same value. find something unique with both of them and give them something that will speak to them individually. say one girl says “oh my gosh I love twilight” or something you can put a lil kit together of different twilight things and then something else for the girl you like. you dont want to get something like jewelry cause that can say a lot of things that you may not want to say. but maybe you get something a little more intimate or romantic for the girl you like and then something you know your friend will love.

I hope that helps best of luck
