Guys are confusing.
D:

So, I have this guy friend, Michael. For awhile... we would barely talk to each other. Some days, we would barely even look at each other! But maybe like a week or two ago... we started talking again. He began to joke around with me... (flirting?)

He started replying to my texts.

Just this morning, he walked up to me while I was at my locker and started a conversation with me. He stayed and conversed with me and my friends.

I dunno..... is he doing this because he likes me or has nothing better to do?

I have a feeling he is single (if he is telling the truth on his myspace. [which says he's single... and is there for friends and dating] :\)
