If you know the "knowing where to tap" story, I have a fun story to show you how this old guy knew where to tap.
My (college age) son is working on developing a web site. React, Google CloudRun functions, the whole bit. Twice he came to me today (because I was working from home) and he's super frustrated. He is getting an error and he doesn't know what to do. He reads the error out to me and says "https". I say "hold on. You're connecting to your emulator on localhost. It's just http." He does that and it works.
Three hours later, he comes back with another mindbending error. I take one look at his code and say "See where you have port 5053? That needs to be 5051". He changes that. and it works.
So twice I fixed his problem by recommending a single letter change. There is no better example of "knowing where to tap." And since my son is smarter than me at programming, I have to celebrate my little victories where I can.
