If in 2022 you still don't know about design patterns (not using them, just knowing about them) I feel sorry for you.
I.e. we don't need to talk about it because we all just do it vs not talking about it and not doing it.
While it’s fine to feel sorry that they weren’t exposed to it, I wouldn’t personally say I feel sorry as I find it hinders people’s willingness to ask for help. Invite questions don’t make people feel bad for not knowing something you or I may think is obvious. We all were beginners at some point.
