Well, the 2 members of her class that she DIDN'T call to refresh her/their memory of THAT NIGHT ...they'll want to get together to hear all the gossip. Small reunion.
My sister called me once in the middle of the night to come pick her up / rescue after some kind of “incident” (when we were teens)
The idea that Ford doesn’t remember how she got home or that anybody who picked her up wouldn’t remember is ABSURD.
