Knit your heart out man! I’m a guy in his 40s who always wanted to get a physics degree. So I’ve bought a bunch of textbooks. Still at the beginning and learning calculus.

I guess it’s partly a desire for privacy and partly social anxiety. Don’t get me wrong, if I were about to shit myself I absolutely would use a public restroom. I’d just prefer to use my own bathroom.

To this day I still don’t shit in public bathrooms.
