Ok, suppose this is the case: you are in a diner with your two darling children, both under the age of four. On the shelf next to the table is one of those evil animatronic plus animals from Hallmark that sings and dances when you push its paw.
The diner is crowded. The tables are close together. The animatronic animal sings "Who Let the Dogs Out."
How many times do you let your kids push the dog's paw?
Zero, because you hate seeing children happy
Zero, because once you start that shit, it never stops
Once, to satisfy their curiosity
3-6, or until you are ready to lose your mind
Until another customer threatens you with bodily harm
Unlimited times, because your children are precious snowflakes who can do no harm and why do people try to quash the joy of little children?
