I don't think my parents personally taught us much - my mother was poorly educated and my father was a quiet man who we didn't react with us that much. However my mother loved books and she made good and widespread choices when it came to the books she bought for us so even left to our own devices we did learn. She was also wise about toys, for example, I got a chemistry set when I was about 11 years old.
My friend said it was OK for her to have little knowledge about science and said there were areas I had little knowledge of. I asked for examples and she said driving and sports.
I said I had a basic knowledge of driving even though I have never driven a car in my life. I roughly know how a car works, what the speed limits are, some of the road rules etc. I have basic knowledge. I admit I am terrible at recognising makes of cars.
I also have some basic knowledge of sports. For example I understand scoring and rules of tennis, the rules and the team names, and some of the players, in Australian Rules football, I have some knowledge of soccer, I played field hockey at school etc.
I guess I am now going to spend all day trying to think of something that I don't have a basic knowledge of.
Edited to add - I know very little about computer programming.
