I’ve been trying to degender my language. I grew up saying “thank you (or excuse me, yes/no, etc) sir/ma’am” and then being in customer facing positions for years just absolutely cemented that in my mind to the point where it is an absolute knee jerk reaction to make assumptions about the gender of others. It’s an awful habit and makes me cringe every time I do it. I try to either just avoid the gender identifier (“thank you.”) which to my mind sounds impolite, or use gender neutral terms like “friend” which REALLY sound impolite. It’s tough but I’m working on it! The real trouble is getting my brain to stop gendering others and as a quite elderly millenial who actually identifies as Agender it is an annoying and difficult task. I’m envious of younger folks who won’t grow up with these kinds of ideas as a default.
