Chemistry, physics -- I never did very well in those classes. However, I seemed to get an "A" in my second marriage. It's been pretty good, considering everything. Both children of alcoholic parents, we've had a lot of issues to deal with over the years. But we've managed to keep laughing and at the bottom line, take responsibility: if there's a difference in opinion, outlook, or taste -- and there always is -- then the "opposing" force is just a flipside of the coin. That somewhere I feel, or he feels the same way. Like he is my mirror, or I am his. So we really aren't that much different from each other. Guess there's chemistry or physics in that!
