ICT (teaching others how to use computer)

I joined ICT one friday afternoon and I was given someone to teach. I thought a guy who does not talk that much. I thought him how to do a powerpoint, how to insert pictures, how to put animations and more in a powerpoint. I tried to talk to him a lot but he just nods every time sometimes he does not respond at all, through this it helped me improve my patients. It also helped me in my confidence with talking to others. He was not as friendly as I thought he would be but he thought me some things too. Teaching him also gave me more understanding to other people, to put myself in their own shoes.
