When you spend 3 months making Halloween costumes for 15 people, then decorate 2 bars on top of that (involving many handmade items and a false wall). Oh, and outdoor tree decorations (flying dementors) because it "sounds fun". Lol, it was, but by the end I was pretty burnt out on it.
Had a "partner in crime", so there were 2 of us, but it was still a ridiculous undertaking.
And to anyone who knows my "infamous moments of hypo/manic", yes, this was when I raised my hands to the sky and shouted, "I'm a f****** genius!!" Over aluminum foil, a Sharpie marker and glue gun.

And ran down the street with a sewing machine (and up and down the street every single time we thought of a new item. Which was about every 5 minutes one day). Haha.
Ahhh, if only all hypo/mania were so fun... Sigh
