Steve phoned earlier to say he'd moved into his new room. So he should be happy - yet he sounded really down. Refused to say why though.

Then he was saying something and I had to ask him to repeat it a few times, because (due to the speakerphone thing) I could only here the wind. He got really angry and shouted at me was I deaf? So I said there was no need to get shirty, and he said, 'well, I'd better let you get back to what you were doing, I'll call you later' in a really nasty way. I just said, 'ok then, bye.'

A few minutes later he phoned back to apologise. Good move on his part because I'd been feeling quite annoyed, although I'd forgotten about it cos Dad was getting me to do his bills. So instead I then felt quite warm towards him. He said he was just feeling a bit down, but didn't know why. I don't necessarily believe he doesn't know why.

So - why?
