So in raising my child, I have the responsibility to teach good manners and how to behave in general. It occurred to me recently that I never really grasped WHY we do some things as a society the way that we do. For instance:
No elbows on the table
Maybe I'm just not high class enough (I have no idea which fork goes where) but I've never personally subscribed to this one. If anything, it's a compliment to how good the food is. How would one eat a 3/4 pound double cheeseburger without putting their elbows on the table?
Don't point
I feel like this is a holdover from the days of the Salem witch trials or something. Pointing is a really effective way to communicate with someone. I could see how pointing to someone and saying something disrespectful could be bad, but surely that's more on the words than the gesture, right?
So what are some "Do"s or "Don't"s you never understood?
You're misunderstanding both of these. The elbows rule is only while you're actually eating. It's fine during chit chat. The idea is to avoid looking like you're shoveling food in your mouth. It's not a big deal unless you're at a formal place.
The pointing thing is to not point at strangers. That's rude as fuck since it means you're talking about them and they know it and can't respond.
