I had a coworker do it to me yesterday.
“Thanks for taking care of that issue with Jeremy.”
“Sure, no problem at all!”
“It’s just weird because he told me the opposite thing yesterday.”
Working on Jeremy’s issue and forget to respond…
“Are you mad at me?”
You KNOW there’s a brothel that constantly brews polyjuice. Bring in a hair from the person you’re attracted to, and have sex with (someone who looks exactly like) them!
You can even obliviate the polyjuice’d person afterwards and leave no evidence behind. Consent in the wizarding world is beyond fucked.
