Just realized

that I have never seen anyone eat peas with a knife in real life, but I’ve read generations of books, cartoons, magazine articles, and humorous rhymes about how you shouldn't do it, but I've never seen anyone actually try to do it in real life.

I suppose there must have been some time period in which it was the norm, then it became backwards and outdated, then it died out completely? Like pouring tea from the cup into the saucer and then drinking from the latter, which I also never seen done in person (Bob Peck did it onstage in Nicholas Nickleby to demonstrate that his character was a salt-of-the-earth, old-fashioned Yorkshire farmer).
