I personally know a (now) little old lady (then, not so much) who had a flat tire out on a lonely stretch of road one day in the early '60s. And who should happen along, but Elvis himself, drivng a big ol' Cadillac. He hopped out and politely asked if he could be of assistance and all she could do was nod, since she was speechless. She thought he would give her a ride to a Service Station (when that's what they still were). Instead, he got the keys out of the ignition, opened the trunk and changed the flat for the good spare! She could barely utter a "thank you". He said, "There's a Texaco just up ahead that'll be glad to fix that flat for you. Tell 'em I sent you." Then he drove off. She went to the Texaco and bashfully told 'em what happened and they fixed her flat for free, checked all the car's fluids, and cleaned the windshield while pumping her $5 worth of gas! They said, "Yep, he's an occassional customer here. He just honked and waved when he came by a while ago."

I remember going to Texaco to buy fifteen cents worth of gas for the lawnmower can. Every spring, they gave away Texaco kites which I liked. Not to mention the free road maps every year.
There used to be a field where we flew our kites. Box kites with long tails went the highest. We were near but not that close to an airport. Every once in a while the cops would come by and order us to lower them. They claimed that they were being picked up on radar.

Explaining the plot of the rock opera Tommy to my father was like explaining [think of your own metaphor]
