Ok, so we've got a thread for why you chose your avatar. But I failed to find one on why you chose your signature line. So here it is.
My signature line currently is:
Gotta Love It.
S:Cam, Eric's gone AGAIN! Cam:Eh, I'll get him in a few minutes. No one is missing him.
I chose the Gotta Love It becuase that's just something I've said for as long as I can remember, and I thought, instead of typing it out 5 times a day, why not make it a signature line?
My other line changes constantly, right now, it's a dialogue between a teacher and a student at my school. The student whined "Cam, [Eric's] gone AGAIN! Get him! We all know where he is, and what he's doing, and it's the middle of class!" (He was making out with his girlfriend.) So the teacher replied "Eh, is anyone mssing him?" There was silence, so he said "OK, I'll get him in a few minutes. I don't think that anyone really cares."
However, I've also had song lyrics, proverbs, and arguments that I've had with friends about absolutely nothing.
Now, it's your turn to share why you thought that your signature line should be.
