I'm 28 and have never in my life used a dishwasher so I relate. We even bought one once and it rotted away from lack of use. I only know what garbage disposals are because of TV and I've never used one of those either. https://twitter.com/elainejgodfrey/status/1125591766965657600 …
My fam used the dishwasher to store dishes. They did not see the point. I did not figure out how to use one until my late 20s. Used to just use a mesh thing to catch non liquid to throw it out in the trash. Did not think the garbage disposal when we did have them was a good idea.
