mom: wave or particle?

I got a text from my mother at 8:10 this morning, finally, after no contact since she blew me off on December 2. All it said was, "Arriving Delta at 5:13. Shall I just cab it? See you tonight"

I wrote back and then heard nothing all day.

So her flight landed ten minutes ago, and I texted her again.

Oh, hey, I finally got a response. Guess I'm heading home to meet her there. Good to know, Mom, thanks.
