Is it normal that whenever I see a girl I like, I automatically think.

Yep. I do that too. I picture us having an apartment, talking in bed at night, coming back from work, doing nasty things in the car... This kind of thing :) I don't even mind if it doesn't happen, imagining these things make me happy :)And who knows, maybe someday our dreams will come true! haha. I think you're just like me. You want to be close to someone, be a team with them :)
