Where Were You?

Sometimes the phone rings at the most inopportune time, that is when you're in the loo. It's difficult to get to the phone on time to answer the call  and I have no choice but to let it ring. After all, if it's important, the caller will surely call back. Sometimes he does, sometimes he doesn't and when he does, I get an annoyed "Where were you?"  I honestly don't think he would want to know.
