One time I bumped into my ex's little sister and she got those shag haircuts that most girls are getting these days. And I blurted out,
"Whoa! I didn't recognize you! No wonder you were looking at me, I was like, hah, that girl has a mullet!"
I don't know, the hairdresser did a very bad job of cutting her hair and I felt so bad for blurting that out because she's a nice person.
Your face has faded but lingers on.
