You may be an exception that tests the rule. I do not have children, but I simply cannot imagine having to go through this stuff right now ( especially seeing what my co-workers are going through ). I do not have the patience to explain things that seem obvious to me. In short, I would not make a good teacher. There is a reason as a society we came up with school as a means to optimize the process somewhat.

I feel you may be a little too harsh though. You may say it is culture, but I would say it is the current situation people find themselves in. Not everyone has the knowledge, skills, time, opportunity and willpower to do what you do.
