Generation gap...

My 80 something year old neighbour lady started laughing at me, as I gave my work truck a wash tonight. She can't understand why I would bother. In the past, other neighbors have told me, that she has said to them, that she thinks my old cars bring the property value down. I feel like telling her to mind her own business, but I just smile to keep the peace. I have a theory, that older people are just angry, that older cars are aging better than they are, and that this pisses them off. Although, I could be wrong, but one things for sure, I will take my old truck any day over her 87' Cutlass...
