Soon I'll have a birthday, so I'd like to arrange the great birthday party and to invite my friends. They'll give me some presents and certainly I like it. 
There are a lot of things I'd like to have. But now I am keen on photography. So the best present for me will be a new camera. It'll give me opportunity to take up qualitative photos. There are a lot of models of cameras, but my favorite is Canon. I saw it in a shop and consultant told me  about its advantages.
I hope to get new Canon, but I think that presents are not so important, as me friend's attention.
