Can't think of any excuses that I've used recently. Most of the time these days I find myself apologizing and saying I was wrong even when I wasn't.

I guess one excuse I've used recently was telling my tennis coach that I am too busy for lessons this month. That is only 85% true, the other 15% is that I didn't feel like it/didn't want to pay for lessons/had other priorities. They won't see it that way, though, and that will probably haunt me when I <i>do</i> return to lessons.
