The sequence of events:

Friday a.m.

Me: What do you want for your snack?

Child: A banana.

Me: *insert banana into backpack*

Friday p.m.

Papers sorted from backpack. Did not search for rogue banana, because why would I?

Saturday

backpack lurked by door

Sunday

backpack lurked by door

Monday a.m.

Me: What do you want for your snack?

Child: Cheddar bunnies.

Me: *insert package of Annie’s Cheddar bunnies into backpack*

Monday p.m.

Child: *sob sob* There was a banana at the bottom of my backpack and it mooshed all over everything!

Me:…The banana you asked for? On Friday?

In conclusion: Bananas are dangerous. Or possibly, when your child makes a healthy snack choice, it’s just a way of getting out the house where she can try to score Cheetohs.
