"Hello," the old man rasps. He smiles eerily at you, showing you his rows and rows of yellow and cracking teeth.
"Eww, I need my space please," you say, stepping back and eyeing his disgusting teeth. "I hope you don't have bad breath, too, otherwise you'll stink the whole place up."
"Was that meant to be a compliment?" he asks.
"No," you say, knowing that you'll probably regret being rude to this weird old fella.
"May I come in?"
You don't know whether or not you should just repent and stop your rude actions and apologise for them or keep going in that rude way.
