You we’re baking cookies. You reach out for the sugar, but realizes you don’t have any. You sigh and decides to go and see your neighbor.

“Hey there. I wasn’t expecting to see anyone.”

You explained the situation. He nods, comes back a few seconds later with the sugar. He had a mischievous smirk on his face.

“I’ll give you the sugar, only if you let me eat your cookie.”
