I am sure my reply would be more along the lines of:
"I'm sorry, but I am going as fast as I can, I will be out of your way as soon as I can"
or
"Shut up bitch, the coffin will wait til you get there."
or
"Perhaps you could help me? I just shit myself, and my nanny has the day off."
but screaming "I'M HANDICAPPED" is not likely to be my first thought of a reply.
Now don't get me wrong. This "old poopyhead" was outta line. Way outta line. There was no need to push the issue, especially if catboy was actually being productive in trying to finish up his purchases in front of her. But his response was downright silly.
