I work in maintenance ā¦Iāll go to some jobs, fix the issue and walk away, Iāll go to some jobs and there will be some troubleshooting and Iāll walk away, other jobs Iāll have to leave and wonāt be able to resolve the issue. The first two Iāll look back on and I might have learned something and Iāll be really happy. The third makes me feel like shit. I remember being the same about linear equations.
FWIW, this is true of the U.K. too. You could also try speaking to your postie.
