Blast from the Past

This happened back in February around Valentine’s Day. Olivia had inquired why the helium-filled heart balloon in our living room was becoming more earthbound with each passing day.

Me: "Olivia, do you know what's in a balloon that makes it float?"

O: "No."

Me: "Well, it's a gas called helium. Can you say 'helium'?"

O: "HEE-lee-yum. It's a gas? Just like my farts?"
