The dumbest thing I ever did (at least RV related) was while closing up and winterizing our seasonal TT at the end of the year. Several hours after arriving home I realized I had left a box of donuts in the kitchen cabinet. After a long night filled with nightmares of extensive vermin infestations caused by the forgotten donuts, I was about to confess to my husband. As I prepared to tell him we had to drive ALL the way back because of my mistake, he surprised me by saying he had forgotten to put down the TV antenna! I didn't say a word about the donuts - just rode along teasing him about his memory loss. When we got to the TT I casually walked out with the box of donuts and offered him one - the look on his face was priceless! At least we are growing old and forgetful together!
