About to get personal?
I'd say they are already here with their insults. Was I there? No. I doubt if Mr. Knowitall was there either.
Let me respond to the full statement... "Were you there or do you believe liars out of habit? "
Do you go out of your way to insult people or are you just a jerk?
I'd likely believe a liar before I'd listen to your poor excuse for what you try to pass off for logic.
