<human>: So, I went to a concert last night and met a guy. He's a friend of a friend, we talked, made out, exchanged phone numbers, went our separate ways. Our mutual friend kept texting me to try to get me to go back out with them after the show (I went to a friend's house and then went home). I turned them down, I was tired and had to get up early. So I texted this guy and told him that I wasn't blowing him off, that I was really tired and needed to sleep but that he should call me sometime. He didn't reply. So how long should I wait for him to call before I call him? There's another show Friday and I was thinking about asking if he wanted to go, so should I wait until, say, Wednesday or Thursday and then ask if I haven't heard from him?

We are both mid-thirty's and I've never gone after a guy before, just waited for them to come to me. My friend said this guy is shy around girls, so I have a feeling I'm going to have to be a bit more aggressive than I normally am and have no idea what to do.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Met a guy, he's shy. Don't know how to peruse him without coming off as a psycho-stalker.
