a very annoying woman

I work an the janitor of our church.......I work from 7am until 12pm. Our preacher is suppose to be in the office from 10 am until 1pm everyday. To give you a little background our preacher is a woman, she has been there for a little over a year now and she is very heard to get along with. Very abrasive hard to talk to unless she sounds like she is jumping our case about something. I try to avoid her as much as possible when we are both there. A few weeks ago she comes and tells me that the electric bill has went from 300 to 600 a month. Well okay.....what am I suppose to do about it? I guess I could quit vacuuming! LOL She has started turning off the air while she is not there. IT gets so hot in there that Jake crys almost the entire time we are there anymore. He use to have a good time playing around in that big old building (it's a huge 3 story church). Well she didn't get in to work today until 15 minutes before I was done. ( She hardly ever gets to work on time she is ALWAYS at least 30 minutes late) She comes in today and turns off the lights were I was working......well hello I was doing something in there. I don't keep the lights on the entire time I am there. I clean a room and turn the lights off -- shut the door as I leave the room. So it's not like I am wasting electric. I just packed up and left. The woman gets on my nerves so much! I can't wait till I can quit . okay just had to vent before I told off the preacher.....didn't think that would be a good thing.
