Clue: What do you normally call "a couple"? A nice couple? A lovely couple? Well, where I come from it usually means a girl and a boy, or a man and a wife - not a threesome!!! (Which means a sexual union of three!) As far as I know most "normal" couples would object to "a bit more" however generous Kelly is to suggest so! I tried once and I almost got it chopped off! We cannot say "a lovely few" for 2 people because it indeed implies more than two (!) Summary: Couple = 2. Few=Three-some! Or four-some! But then you got to ask how many is "some"? Hehehee....

Good question. One definition of couple is literally "two", as in a married couple. However it can sometimes be used to mean slightly more than 2. A few by definition is more than 2, but not many. So I usually use "a couple" meaning 2 or 3, and I use "a few" to mean 3 or 4 or 5.

There are differences in use here between the US and the UK. In the UK, a "couple" is pretty much exclusively used to mean two and a "few" can be 3 or more. Where I am from in the US, a "couple" can mean more than two (a couple of days could be 2-4 days) while a "few" would be more than a couple but there is some overlap. If I am going on a short vacation for 4 days, I'm equally likely to say "I'm going away for a few days but I'll call you when I get back" or "I've only got a couple of days, what do you recommend I see?" As you can see from the answers you're getting, there is a big range in how native speakers use these terms!

A few days, in my opinion, means 2-3 days. A couple of days means a bit more, maybe 3-4 days.
