So my best friend of 12 years lives 2000 miles away. I flew out to visit last week, but spent very little time with him because he was sick. But he was still responding to my texts, calls, and e-mails. He apologized profusely for not being able to hang out while I was there. This week he's been ignoring me, and I can't think of anything I could have possibly done last week to merit it. It's really starting to piss me off.
