I’ve never told anyone IRL that I use Linux.

Nor have I actually spoken to anyone for more than a few words since I started using Linux.

I just generally try to avoid letting people know how technically savvy I am. I’d rather not do basic tech support for everyone I know.
The magic words I use are, “Oh! This isn’t Linux. I’m not sure how to use these, anymore.”
If anyone irl asks, I’m “trying to learn how to use Linux”. Which is technically true, I still learn new things all the time!
