What dead traditions/customs would you bring back from the Downton era?

I'll admit, for me the answer is "not much"--it's a fun show to watch but the rampant classism, limited roles for women, sexual double standards and the sheer difficulty of day to day life (I can barely drag myself to make a peanut butter and jelly sandwich some days, imagine having to make everything from scratch) can stay in the Edwardian era. Not to mention antibiotics and vaccines! Antibiotics might be at the very top of the list for why I'll stay in the 21st century, thanks.

But things I would bring back:

1) Formal mourning. I think there's something valuable in having a physical symbol that says "someone has died so I'm not really my usual self, please treat me gently."

2) Handwritten notes. I want all my correspondence on monogrammed stationery, thanks (except bills and work stuff, I guess those can keep coming by email).

3) I don't want to dress for dinner EVERY night, but I'd like to bring back some sense of things being an occasion. People don't dress for dinner or even for church anymore. I think I'd like having more occasions that we mark as significant by dressing for them.

What about you, what would you bring back?
