How do you explain your fascination to X about Y

[asagaai]

So I did an oil change to my XR8 recently, and put in 5w20 Nulon full synthetic. The engine definitely to my feel of the bum pulls harder, with more torque, than the Castrol Edge stuff.

So Supercheap auto had 25% off the stuff to members, so I bought out 1 shop stock Saturday, another shop Sunday, and I have a number of bottles in the kitchen bench to be stored in shed, and I am looking at the honey thickness up to lights (seems slightly thicker than the Castrol Edge) and reading the label about Molybedium and feeling so chuffed with my purchase.

My smart **** daughter, who goes to Uni, and truth be told has acquired more distinctions in 1 year than I achieved over 2 degrees, looks at me with a slightly ridiculing curl of the lip and says what possibly can you find so interesting with those bottles.

I mumbled something about this oil giving me more torque and the car pulling harder, her eyes glaze over in the confirmation she is talking to the local village idiot.

Has anyone else funny stories where they have been very interested and fascinated with X, and failed miserably to explain the obsession with a non believer?
