(Note: I am a personal trainer for this gym member, who has always been a little strange.)

Gym member: “You always make me do difficult things!”

Me: *joking* “Yeah, I’m sinister like that.”

Gym member: “I don’t know what that means, so don’t tell me!”

Me: “Okay.”

(The next day, the same member comes into the gym with a look of panic on her face.)

Gym member: “I went home and looked up sinister. You’re not sinister, you’re lovely!”

Me: “No, it’s okay. I was kidding!”

Gym member: “But sinister means evil! I do not have an evil personal trainer! You’re lovely! You’re lovely!!”

Me: “Thanks!”

Gym member: “Oh, you’re welcome sweetie. I’ll see you next week, but never say sinister again!”
