Hang up

I never hang up on people's phonecalls ever. Not unless the other party asks me to hang up first, or it's a mutual hanging up. But I did it last night for a phone call. I can't believe I've turned so rude. Then again, I've practically never had calls where I said so few words. People usually call me when they have problems so I say a lot of various analysis and solutions to them. Or they call because they were bored and so usually they have a lot to say, and me a lot to counter reply. Last night was an exception. Totally out of the blues.
