Don't do it. Just ignore him. You'll thank me.
Look. If you aren't comfortable speaking with a 'voice' more than a face, and you aren't comfortable with this, then tell him you don't want to speak with him on the pone. If he gives you a hard time then *IGNORE* him, because clearly he is going to prove to be a nuisance because he doesn't *listen* to you<br />
Sorry, I read you wrong. I thought you said you wasn't comfortable about it? If he was a good friend he wouldn't keep bothering you. Anyway ...
