I've noticed that I don't need to do anything "big" with the other person to feel content. It could be as simple as watching tv or just going for a walk. It's more about spending time getting to know the other person rather than spending money and doing lots of activities together.
Like Bella said, I hate it when other people know that I like them...it makes me feel really vulnerable and exposed (especially if I have no idea how they feel towards me). It is annoying though keeping all those emotions bottled up inside. I don't go out of the way for them not to notice, and I usually don't even care if others know. It's just taking that first step to let the other person know that you like them. It's a high-risk high-reward/loss situation, and I don't like risk Bummer. Taking the initiative in that department terrifies me.
Also, I'll +1 what Cimarron said about physical intimacy. It's not happening until I know you like me and we've talked about it to some extent. I'll give hugs, but that's where it stops.
