You can help young people in many many different way, from teaching them to tell the time, or with more serious situations.
The most rewarding session I have had is teaching a ten year old how to read. I'll never forget that!
It's the best when young people appriciaate the help and advice you can offer. It never fails to make me smile. I have had two young people tell me I am their role model. That bought tears to my eyes.
