Was that the smoke detector... NO... it's the Lunch Bell!!

So, my sister's smoke detector is EXTREMELY SENSITIVE!! It goes off during cooking more times that not. You could be making toast (NOT burnt) and it will go off. Quite annoying, but we make do. (It doesn't help that it's right beside the kitchen).
Anyways... the other day we were cooking dinner... the smoke detector starts beeping (and it's definately not quiet)... down in the living room we hear Lynzie yell (as she starts running to the kitchen)... "LUNCH TIME"!!!
Apparently my sweet little girl thinks our smoke detector is our lunch bell. So funny and so sad!!
