Fire Detector

So it was Sunday night, and for some reason on Sundays I have a really hard time getting to sleep, I think I am just thinking about the week and everything that has to be done by the end of it. So it was about 10ish that I went to bed, let me remind you I attempt to get up at 4:30 so I really need to get to bed pretty early. So I am tossing and turning then I hear this beep every so often, and I am like what in the world could that be... So I get up and find out its my fire detector, but there was a little bit of a problem.... I don't have a ladder, and my ceilings are vaulted so I am thinking I am in trouble. I get my dinning room table chair, and am so grateful the guy at RC Willey talked me into getting a counter height table because that makes the chairs a bit higher. Stand on the chair, and realize I am too short to reach the dumb thing. So I get a knife from the kitchen and think maybe I can shut it off with that. Not so much...So I its like 11 now and I realize I have a step stool, sore I put the step stool on the chair and then get on top of there, I can finally reach the fire detector so I take the battery out, and the blasted thing continues to beep. I am so frustrated now, I try pulling the wires out of the wall. Not knowing what to do I call the only guy who I know who I work with who I know would be up that late practically in tears, and he says well you've got to put a new battery in it so it will stop beeping. So at 11:15ish I get dressed again run to the 7-11 down the street, to buy 1 9v battery for $4.30. I put the thing in and I finally get to sleep at 12 midnight, only to wake up a few hours later, what a way to start the new week.
