Phone Etiquette

This afternoon I received a phone call from a friend (who will remain nameless) - I had a lot of work to do but I hadn't talk to him a while so I answered the phone. During the majority of the conversation I felt like I was talking to myself, he was as he said sending an e-mail.

Now generally I wouldn't have a problem with this but as I reminded him - "you called me". The moral of this story: don't call a friend unless you really are interested in speaking with him/her or you're just wasting his/her and your time.
