Outdated "manners" you'd like to see go away

You are a very "inward" observing person. At no point in my day do I look around and feel that society's problem is too much polite behavior...

1) This is manners born from practicality. People who put their elbows on the table tend to place their body weight on the table. Certain tables will tip, depending on how they're stabilized. It's probably less manners and more so you don't make an *** out of yourself to keep elbows off the table. Sure I guess you could look under every table to see how it's stabilized, but it's probably a better habit to just keep them off.

2) Holding open a door is basic civility. Unless someone is far away, it's expected and not unreasonable. I guess you can close it in their face, but that's a **** move. I'm not sure why gender matters here.

3) Thanking someone again is basic civility. I can't think of a single reason to not do it as it takes no effort. I'm 43 and it's basically automatic. What is the argument exactly for not doing this again? We don't thank people nearly enough in society. Kindness, however redundant it may feel is never a bad thing.

4) That's not manners. That's privacy. Feel free to share your income if you wish. It's only rude if you ask someone else for their pay information. Now, if there is actual concern for equal pay and you are looking for the information to form an argument to your employer for additional pay then I would encourage you to speak privately with the individual(s) and offer to share yours first in good faith.

As far as outdated manners, I can add that a woman should stand (just like men) during an introduction, there's no need to ask a father's "permission" to marry their daughter and keeping a napkin in your lap isn't really necessary. Although I will always remove a hat/cap when indoors, I understand that's not necessarily everyone's view. It doesn't bother me at all.
