Forgetting it was Friday. Then not realizing how late in the day it was. Which means that if I do any banking, nothing will hit until Monday. It also means that calling a business at 6:05pm meant getting the message, "...our business hours are 9am to 6pm..." *click* Which compounded with the banking thing pissed me off.
But writing it here made me laugh, so my non-gripe thing is free anger management therapy in the Gripe of the Day thread.
