When we went to turn on the air conditioner, we couldn't. No, it wasn't broken. . . . the knobs were missing. There was nothing there except two little stubs. I asked my husband if he took the knobs off so the children couldn't play with the air conditioner and he replied that he did not. Then we asked each of our three children and they all replied with a "no." I still thought maybe one of the children did it, but we had no way to know for sure.
I feel terrible for suspecting the children all these months.
