I say tell her you got a raise, get a b.j. , and call it special. Don't make a big deal about it, so shwe doesn't thin k it's a lot. If she asks just give round-a-bout answers. No details. If she is the normal woman, she will need to know every detail, but just tell her it's best for all of mankind if you don't disclose the information. If she pesists, reply with (in Jack Nickolson voice) YOU CAN'T HANDLE THE TRUTH".
