"i think i have the key..."

yesterday i left school without checking for my keys. i left them in to the lock of my closet in the art classroom. when i reached my home door i had to call my sis for her to come home and let me in. after finishing the trip with mr.C i allso used my sis as the key to let me in. but now! everyone has left home, the door is locked, and I CAN'T GET OUT!! HOW CAN I BE SO STUPID??!! at least i have some good friends who will unlock me and take me to school... :P stupid, huh?!
