almost fired!

can you believe it?! so friday of last week i was called into nichole's (my new boss) office. i wondered what could i have done... well, apparently i'm not allowed to do good things for people!!! here's the story...
i ended up staying late at work on wed and had to close with a fellow co-worker. her boyfriend had left the lights on and the battery died so he was calling to say he'd be late, waaaay late. i didn't want to make the other teacher wait, cuz she would have, so i said that i'd drive her up to where he was and take the other way home. not a big deal right? well, it was her and her baby just to let you know. still wondering? apparently i can't do that because it's against code of conduct for the Y. i was brought into the office and given a "verbal reminder" not to do it again. good thing i didn't get written up, i would've been fired! the thing i don't get is why it was wrong... it was after work hours and she was in the car with me. my other co-workers don't agree that this was fair either. i'm gonna seek it out further and look into why. what do you think?
i guess i should just be grateful that i have a job...
