What are signs that a guy shows he is interested in a girl?

Guys are the easiest creatures to figure out. We make it very obvious. we ask you to dinner. We constantly want to do things for you. We come up with stupid reasons to come and talk to you.

You get the idea.

Here is a sure fire way to find out if he likes you. Ask him. trust me, he won't be offended. If he is a normal guy, he will be flattered, and you will get your answer. Most guys like the direct approach. Use some tact though. Pull them away from their friends and ask him when he is alone.

Hope this helps.
