Grin and Bear It

A family of four having a picnic is surprised,
When a hungry bear enters the camp site looking for food,
Approaching them so nonchalantly and pretty calm,
Right up to the table, impolitely and a bit rude.
The father then begins to grin nervously thinking,
“If I smile the bear will see I’m friendly and go away”
The bear thinks “showing teeth is a sign of aggression,
Now I’ll have to eat them all just like a buffet.”
