ITS X-MAS... gifts... gifts... gifts!!!!
The size of the gift or the price of it doesnt matter... try get her something that u know is special to her, and that she would love. And if u know this girl for a year, u should KNOW what is "special" to her and what she "likes".
Eg: If this girl likes Chocolate, then buy her a box of chocolates that are maybe heart shaped etc with a small card saying something along the lines of "These chocolates remind me of u, sweet,beautiful, and full of love". ( I did this once, and the girl seemed as if she fell in love with me right there & then
By doing this, u are giving her something that is "special" to her (or that she likes
alot ) and u are making HER feel special too, what more can she ask for?
I think u get what i'm trying tp say, so good luck, and have a great X-mas!
