eh. Just start calling Know-It-All Cliff. You know, the postman on Cheers? Actually, he reminds me of my nephew's sperm donor. After my husband and I met him the first time we decided he must have been about 80 years old because everytime someone mentioned any occupation or hobby, he had done it for a career for at least 15 years. I don't blame my sister too much, she'd just gotten out of a bad marriage and as awful as SD was, he was several rungs up the evolutionary ladder from the evil ex (who still lives with his mom in his 50's btw.)
