Recently, I saw a toddler ask her mom why a snowman decoration was wearing a scarf. And the mom decided to go the playful route and said that the snowman is probably cold. So, the toddler followed up asking why the snowman is out here and not inside the house, where it's warm? To which the mom replied that it would melt, if it was inside...well, uh, not this one, as it's a decoration made out of wood.
And like, yeah, these are some tough questions.
Do you just explain to a toddler that humans put up decorations, which don't always make infinite sense?
