Dude... I've been there...
it wasn't long ago, standing in the grocery aisle, and older gentleman was trying to push his shopping cart by mine. Well, he says, excuse me, and coughed... He looked a little sick but I wasn't going to go down like that if this was some kind of insult.... so I looked him in the eye and said "you've found me."
It got a little hairy, and I was holding a can of lima beans in a death grip, but he passed on by and gave me a couple quick look backs while muttering under his breath about the world today...
I told him "Outside NOW!" But he said something about being a crazy SOB... I sat there, thinking about what could have happened, how quickly that escalated...
Slowly, my mind had shifted to my grocery list and with a sigh of relief, I went to find the tampon aisle for the heavy flow days...
So, yeah, Agent... I've been there...:SIB
