Think it was Leno last night that said
‘I used to be afraid and nervous when I ran into my teacher at the grocery store’.
Wasn’t the ‘going fear’ that the ONLY reason she was in THAT store, at THAT time is she wanted to ‘ambush’ your Mother?
So, your job was to keep them apart.
You didn’t have to be ‘guilty’ of anything, you just knew you were.
Back when I was in college, I went home to podunkville during the Thanksgiving break. As I was in the grocery checkout, my married American History professor and a gal from class stepped in line behind me.
