And it is general (Off-Topic)

People seem to say "A couple" when they know it's two. People might say "A few" when the number is unknown (or can't be bothered with) and it may be 2, or it may be 3 or 4.

For example, if I say:
"I had Chinese food a couple days ago"
and you say:
"You had it Saturday, you liar!"
I'd probably tell you to do something that isn't PG rated :)
But the deal in that instance is not that I knew it was recent but it wasn't yesterday. So without thinking further I go with the sentence that means "sometime in the last week".
