is it ok to call a woman "sir"
Only if she asks you to.
like sometimes i’ll see a woman at the store or talk to a woman and i’ll say “excuse me, sir”.
Stop doing this.
I'm in this post and I don't like it.
It's a fine username but I'm not overly attached to it.
I use different usernames for different services and try not to use the same one twice. I do tend to follow a "theme" (though how they all relate is a secret) with them but that's about it.
I think that having a "consistent" online identity across different services isn't very safe but I'm sure that's coloured by my own personal experiences. 🤷♀️
