Besides everything else, Martin Luther King gave us a sorely-needed January holiday. If you want to do it right, make plans to do something selfless that day. It might even lead to you continuing to do that thing or work with that group, and exercise those human kindness muscles, developing the content of your character. Or it might just be the once, and that’s okay. Or maybe the best you can muster is to raise a glass and thank Martin for the 3-day weekend. It’s still something to get your head past this slump. By Groundhog Day you’ll be seeing that little bit more daylight that brings hope.
I’m over 60, growing up in SoCal we had Square Dancing and the Maypole but also the Mexican Hat Dance, plus Tinikling, the Filipino one with two poles. Oh, and I think a bit of Hula.
(Later as a teacher I taught my 2nd graders some Russian dancing I had learned from my ballet teacher, because little kids are bouncy and kicky and we could do it inside when it rained.)
If you mean the mail slot, it’s perhaps old-fashioned, since it’s a security weakness.
I remember seeing an old movie where a family kept the house key on a string just inside, so when the kid got home from school they could reach in, get the key, and unlock the door (parents were at work).
And a couple where someone put fire or explosives through the slot.
