There still comes a point where you need to engage your brain before speaking first.
The the other week just after church service, we're breaking everything down (start up church at a school) and the one guy is pushing paperwork into his wife's plastic case (she's a school teacher), and you can see he's having to use some force because things are getting tight per paperwork in the box being stored vertically.
His wife is watching him and tells him "be careful and don't stretch my box out!"
I immediately responded that I would touch that comment with a 10' pole...
I immediately apologized for the comment... Luckily people were chuckling and not just staring at me...
