When Mr. Fairway and I were first married and the world was very young, I was always struck by my MIL's concern for her three kids. Even though all three were grown, with families of their own, she couldn't sleep at night when they were visiting; that is, until one or the other knocked on her bedroom door, stuck his head in, and whispered, "Mom, we're back."
I've carried on that tradition, but with a special twist. I'm usually on-edge not when they're home, but when they're traveling.
Ella Numera Dos just winged her way back to college and is now safely ensconced in the profundities of campus life; Ella Numera Una finally made it back after 10 days in Ireland, including a Dublin pub crawl on St. Patty's Day (more on that, I'm sure, later). That's one of the Irish seascapes, above, that she captured during her sojourn.
Got the last call a few minutes ago; both gals are back on home soil, and although they're not at "home," per se, they've "reached." I have no worries for now, ascribing to the anoymous quote that dictates, "Today is the tomorrow we worried about yesterday."
Or, as Bobby McFerrin likes to say, "Don't worry; be happy."
