The following is an actual conversation between my only son and me.
ActorBoy: I'm supposed to give them several available dates and times...as long as it's in these four days. [Pause] I don't think I can fit "several" dates in that amount of time.
Me: Sure you can. Three is "several."
ActorBoy: Three is "a few."
Me: Okay...let me think...two would be "a pair," three is "a few"...how about four? Four could be "several."
ActorBoy: I would call that "some." I've always connected the number twelve with "several."
Me: Well, sure, twelve would be several, but it doesn't take that many to be "several." I could have dinner with eight friends and say "I had dinner with several friends."
ActorBoy: I would call that "a bunch."
ActorBoy: You should write this down!
