If there are any car guys in the family, simply tell them it's sorta like that. Tinkering is a totally valid hobby, but older people have an easier time understanding it with cars (because cars have been around longer, mostly :P)
Or you start fixing something, and you find 3 other problems, not related to the one you started fixing 😂. You just didn't know about them cuz you usually don't use libfoo for the thing you currently need 😂.
It's like going to the doctor for a checkup and finding out you have diabetes 😂... I mean... it's not good, but better now than later, right 🤷 😂.
