We made things, or repaired things, or took things apart, then reassembled them to see if we could. I truly believe that much of what I do today, I learned by those childhood experiences, and from my dear old dad, taking the time to explain what he was doing when he repaired the family car himself, or the plumbing in the house, or the electrical, or whatever. We had no money, so we had to learn to take care of our own stuff. WOW, how did we get along without a 2-way phone, or text messages, or for that matter T.V.? Amazing isn't it?
