W friend who was a tradesman how to properly size extension cords (which he used often). I tried to tell him what gauge cord was needed for a certain number of amps. His reply was "I don't need to know that; I just buy the fattest one I can find."
Oh LoL Magnum that's my husbands obsession he is always telling me off for using the wrong one!

I certainly got invited to more stuff than my worldly peers when I was young ...we had cong parties, which was nice. We had music and food and did dances like the conga LoL! Lots of weddings, and dinners of course.
I think in the 70s and 80s it was easier to mix in if you were not born in ( someone mentioned born in cliques, which I think are a thing now more so), people were open and this frightful phrase " not of our sort"( Paul sometimes I could throttle you) was not bandied about as it is now!!
When I moved to London my first cong in South East London was horrible, run by spiteful Cypriot elders and their wives. Ignorant council house snobs I'd never met such people before.
Of course the minute you don't attend weekly the invites disappear. They seem friendly when they see you, but they never make contact.
