Maybe I should completely ditch it, and use the informal one with everyone new, just with the hopes of building immediate rapport. I must not be the only one to hate it, and surely those people who would mind me using the informal one are not worth my time in the first place.
Luckily we don't have gendered pronouns though, so we can avoid that problem altogether.
I think in the end best and most scalable language is the one that avoids having any implications in the "you" or "pronouns". We are all humans after all.
