Be honest, don't come up with bullshit. Tell the truth, but if you can't stand the other person cry, then do it over the phone. Order a good wine, drink, and hopefully, after a glass or two you can relax. Or, if no alcohol, talk about a good movie you just saw or a good CD you just bought.
Roses are red, Violets are blue.
Go to a good movie. You don't have to talk much, but afterwards you can discuss about it. Hello, this is the 21st century, you know. Both of you. Nope, if you have the same interest it can be fun.
