I expected to run into this guy the other day, and planned to ask him if he was interested in a concert ticket for this sunday, for a concert with me and a few friends (I ended up having 3 extra tickets) and then seeing if he wanted to get together and study for our test on Monday. I didn't end up running into him so I tried calling him 3 or 4 times, but every time I got an immediate recording (after no rings) of "This person's inbox is full, please hang up". So I emailed him yesterday with the invitations. Thing is, I don't think he has a computer at his apt, so he might not even get it until Monday. Should I call him again now (assuming he'd pick up or I could leave a message)?
