That probably happens somewhere not on the Internet

That really depends. My wife cuddled me pretty heavily a lot of the weekend, and grabbed me while I was trying to get up and go to work, but for other people it was Friday. I went out to a bar and saw people being affectionate, both romantically and platonically. In fact "who hates whom contests" are something I see from time to time among people I know IRL, but it's more of an every other month or so thing, not the default social interaction.
