I'm with Laurie and Beth, fortunate enough to still have my father. He is a Baptist minister, so conservative he makes some of the conservatives on this board look like lefties!
While our perspectives are very different on very many things, I will always be grateful for the enduring lessons he taught me, more by example than sermon. These are a few: Be able to defend your position; remember that people are created in God's image - treat them with dignity; know the difference between a mistake and a bad choice; learn to laugh at yourself; turn the other cheek; don't be afraid to admit when you are wrong; listen; take time for yourself so that you can be in a position to help others; ask for help when you need it.
We still spend many a dinner hour debating everything from politics to religion (often to the annoyance of anyone else present), but we agree on the important stuff.
Happy Father's Day, Daddy.
