I remember asking my mom that question when I was a teenager (lo, those many years). Her response has always stuck with me. See, Babs washes the Donald's hair in the sink each night. After cleaning up the kitchen from dinner, she pulls a couple of towels out of the linen closet and puts them on the table. She puts the nicer one (you know how there's always a more raggedy towel) on top, to be used by the Donald. That, she told me, is love. When you want the best for the other person. You know what else she told me? The Donald always switches them, so the nicer one is waiting for her. There may be other ways to define love, but that's the one I cherish. And, heck, they're going to celebrate 50 years of marriage before too long. I guess they oughta know.
Happy Valentine's Day, my loveys.
