I completely forgot about one of my OTHER least favorite things that occasionally gets said to me! Thankfully, Heidi reminded me in the comments section on my last post.
Any variation on:
"Hey lemme show you this cool magic trick I just learned..."
You can also substitute "card trick" for "magic trick" because I dislike both intensely. Oh! And jokes. Boy do I get nervous when someone tells me they have a great joke I need to hear.
On the flip side, when I tell people that I hate magic tricks, card tricks and pretty much all jokes, this in turn alienates THEM.
