Coat Check LOST my brain!

Well today was a total write off for me. locked myself out of the school I was at..without my coat. Had to call my parents to borrow a coat..my supervisors were AWOL ao had to get a locksmith. And the SAD part was we BOTH knew how to break into the joint.. WITHOUT keys! so we got backinto the school in under 3 minutes once he showed up! but still.. I walk out a LOCKED door, and don't UNLOCK it.. and expect to be able to get back INTO the building!

AAAARRGHHH!

Coat check girl.. can I have my brain back please?
