I think everybody who does Photography as a Hobby or a Profession at one time or another teaches someone how to use a camera or take pictures. I love to teach people about photography, we can share "secrets" together and get smarter together, it's amazing how it works.
Tip: when you take pictures of people, as a general rule try to keep the camera on the same level as the eyes of your subject. One exception to this rule, when taking pictures of women have the camera slightly above your subjects eyes. Another exception to this rule, when taking pictures of men have the camera slightly below the eyes. Try it, it's really fun.
General rule example:
I don't like to put pictures of kids on the web for safety and security reasons... but that being said here is a picture of my son taking a picture, great form :)
