I've got a friend from Scotland, so one day while I was speaking with him, he said a phrase I didn't understand. I asked him if he had a girlfriend and his answer was this:
"I wish, I'm as single as they come"
What does it mean?
"I wish." = "I should be so lucky." "If only." It is one of those phrases that can be used to express a sense of being unlucky in something.
"I'm as single as they come" = I have not yet found someone to get together with; I am happy not being tied down.
