The onion lost his friends!

This is literally the conversation I overheard in the grocery store this evening:

Father: "We need some onions."
Little girl: "One onion?"
Father: "Why don't you get a big bag?"
Little girl: "Okay!"
Little girl: "Daddy, look! Here's one onion that's not in a bag! He must have lost his friends!"
Father (not listening): "Do you have the onions?"
Little girl: "Daddy, can we take this onion home? He's lonely!"
Father: "Just take the bag!"

I wanted to interfere and either tell the little girl to put the onion back with his onion friends in the single-onion stash - or tell the father to just buy the darn extra onion.
