Write your question down before the meeting and read it out loud, no matter who talked first.

finally saw what was causing it" makes for a good story, but two years is a long time to reach that point. Chafing shows up fast, like fuzz on the loom tape or a shiny spot on the insulation, and a quick look every few months would've caught it way earlier. A full teardown after 24 months is fine if the harness was buried behind a bunch of stuff, but for a normal run that just sounds like nobody was checking.

Three weeks is about how long it takes for a nail to grow out from the matrix to the free edge, so you basically watched one full cycle of new growth. That means the peeling would have stopped on its own around the same time no matter what you put on it. Cuticle oil does help keep the nail plate flexible, sure, but the peeling you had was probably from the gel removal, not dryness, and oil can't glue split layers back together. If it was really fixing the problem, you would have seen the peeling stop keeping pace with new growth, not all at once at the three week mark. What likely happened is your nails just grew past the damaged part. Save your $8 next time and spend it on a gentler removal method instead.
