Earlier quoted context omitted.
"couple" and "few" are debatable, but thanks to Survivor we know definitively that "several" means seven.
Couple is not really debatable - it has a definition that includes 2. Not 2 or 3, or any more than 2. Just 2.
I remember being confused as a kid what the difference is between a couple and a few. Turns out sometimes there is no difference.
