I can just imagine tomorrow at work:

“Hey Ms Caroline, I saw you at [local supermarket]. I thought you were waving at me at first but you weren’t. Why were you waving at a cart?”

True Life: I become emotionally attached to inanimate objects.

But on a serious note, it just was slowly rolling away and I thought it was the funniest thing ever and it was heading into the forest of no return so I waved it a goodbye. Is that so bad?
