dear guy with your hand down the back of your pants...
There are some things that are clearly not acceptable.
Clearly.
One of those unacceptable things is walking around your kid's school with your hand down the back of your pants. I mean seriously guy. What the hell is wrong with you? You can't keep your hand out of your ass crack long enough to get your kid in the building? It's close quarters in there and I don't need to see that... or to watch you elbow the poor kid next to you in the head as you extricate your hand from your crevice!
Seriously! Keep your hand out of your pants. Front or back. Knock it off. Don't you have pockets? Or self control?
