"And that is why..."

I was standing in line with my frozen Coke at the convenience store just now. Ahead of me were a mother and a child about 2-3 years old.

Salesclerk: That will be $27.98.

Mother: I only owe you $7.99.

Salesclerk: I'm including the cell charger that your child is chewing on.

Mother: That isn't ours. We don't want that.

Salesclerk: Then you shouldn't have let your child open and chew on it.

Mother: You shouldn't have had it where he could reach it.

Salesclerk: That will be $27.98.

Mother: (storms out of store without her groceries, throwing the cell charger on the counter)

Me: And that is why...

Antinatalist friend a/k/a salesclerk: ...we never had children.

Antinatalist, extinctionist, efilist... I've tried not to be a misanthrope, but misanthropy is taking over my brain!
