Yeah idk. I spend a inordinate amount of time talking about tides and watching them, but generally only high and low are focused on because the midtide is when the water is changing the fastest. The water spends more time at high or low than it does I. the middle, so it's not really noticable.
I grew up on the coast, so I never really thought about tides just that that was the way it was. Then I married someone from a landlocked country and every time we drive over the bridge over the cove near our house I comment when the tide is high or low since they are used to lakes, and I'm never quite sure what to say when it's in the middle.
I didn't grow up at the coast, but I learned about the tides the hard way (we found a nice place at the beach at low tide, and had to seriously hurry to get everything to safety). That taught me about tides.
Last year we were visiting a coastal town in the UK, and I had checked the tide table beforehand so I could always tell my wife and our friend about the current state. Sadly, we never had the time to see the beach or the port there - whenever we had time, it was already dark.
Growing up, we had a game called "fight the tide" where we would build sand castles in the intertidal zone with a stick in the peak of the castle. Last stick standing wins a chocolate bar.
