Look, I know that “sir” is generally seen as a sign of respect that can potentially be gender neutral (but obviously leans towards men). However, that doesn’t stop me from feeling a blow to my ego when you use it to address me.
I at least hope that my profile picture does not look like a “sir.”
Some guy used this to address me 3 times.
Please try not to address a female as “sir.” We tend to not like it.
