Is he giving me 'the signs'?

It's hard to tell. These can be signs that he likes you. These may also be signs that you are watching every move he makes and overanalyzing them. Fact is, you have to start a conversation with him or this is going nowhere. A few ideas? Crowded bus, step on his foot. Or drop your books...if he's any kind of a gentleman he'll help you pick them up, then you can say thank you...and now the ice has been broken.
