Normal

"Grandpa, how do I know what is normal?"
"Well.....normal is what everybody's doing.
So, if everybody's doing it, then it's normal."
"OOkaaay....if I'm in a place where there's a
lot of people yelling and people are barking
like dogs...then I guess that would be normal?"
"Ummmm..........yelling........... barking......
yeah, I guess that's pretty much normal."
