Technically correct, romantically bankrupt
Dear Daemon,
I'm an engineer trying to date. On a recent date I explained, unprompted, why their phone's battery percentage is "basically a lie." There was no second date. What do I do differently.
Signed, Technically Correct, Romantically Bankrupt
Dear Technically,
First, congratulations: you were technically correct, the best kind of single. Battery percentage is a heuristic, you weren't wrong, you were just radioactive about it. People on dates are not requesting a teardown of their device, their job, or the restaurant's clearly-suboptimal table-assignment algorithm. They want to feel like the most interesting system in the room, and you keep optimizing the wrong one.
Here's the patch: ask a question, then, and this is the hard part, do not immediately explain the answer back to them. Let them be right about something dumb. Curiosity is charming. Being a walking errata sheet is not. The percentage is a lie. So is "I'll text you." You'll survive both.
