June 12: chronoptimist

A person who always under estimates the time necessary to do something or get somewhere.

“Hey, Cindy. you know my parents are expecting us in 20 minutes.”
“No problem. I just have to wash the dishes, take a shower, do my hair, walk the dog and then I’m all good to go. See you in 15.”
“You are such a chronoptimist! I’ll see you in 45.”

I think this is the opposite of the Scotty Syndrome. You overestimate the time a job will take and then look like a hero when you do it in less.
Gawd I miss Star Trek.
