a "great" day

The way we use language is entertaining to me. Like when people use sarcasm....here's a funny memory of mine.
I meet up with a friend, who say, "Man I'm having a great day".
I say, "What do you mean?"
Friend replies, "This morning my car had to get jump started, then on the way here, I get a speeding ticket".
To which I say, "See? That's the difference between you and I, you have such a positive attitude. If it were me and my car had to get jump started AND I got a speeding ticket, that'd be a bad day"
