If a tree falls in the woods, does it make a sound if no one is there to hear it? (old saying)
You ask "what if they are" hearing impaired.....The hearing impaired person cannot hear the nasty remark, so no harm done even though it was a very rude response. Hopefully, the person WAS hearing impaired so the person in need of toilet paper got NONE. LOL
If I were the person who did not respond and heard that nasty remark, I would pretend I WAS deaf.
Stranded, stranded on the toilet bowl,
what do you do when you are stranded
and do not have a roll?
Well, you can sit and wait for the rest
of your life, or you can be a man
and wipe with your hand.
That silly saying was a childhood rhyme for those without toilet paper. LOL
