"It's good psychology to keep a box of facial tissues in the bathroom, when having guests. Most women will thoughtfully use these, instead of guest towels, to remove excess lipstick."
Oops, sorry Sally. I just couldn't wait to put on some more lipstick, and of course I needed to blot it. I didn't see a box of tissue handy, so I just used your guest towel. Hope you don't mind!
