Maggie's post about her plane ride was interesting. And scary. And enlightening. From now on I will have a scarf with me on a plane. And when I have kids, a Sharpie. For this:
"On a side note, when we were kids, my father would travel with a Sharpie so he could write on us if something ever happened. Like being separated, he would write our names on our left palms before we got on a plane."
(From one of the comments on that post).
