AL,

I got up on the wrong side of the bed this morning. (Actually, I just
finished helping someone with a Master's degree turn the paper he's
trying to write into comprehensible English. That's worse.) What it
boils down to is losing the restraint that would normally deter me from
this question: how does someone who has reached the senior year in a
university come to write "tempo's" when he means "tempos". There's a
very clever (but a bit over wordy) book by Lynne Truss (she's English
too) called "Eats, Shoots, and Leaves" that you would do well to read.
