People claps when I practice in Delhi Metro

I am educating people about TISA and How it is helping stammerers in Delhi metro twice a day, when I go to office and then on return journey.I used to give a mini speech on approximately 2 minutes in between any of the 2 stations and most of the times, people do listen to me sensibly and some times, they even clap to motivate me.

Practicing since last 1 month, I am pretty confident in doing it now.And, I am planning some further challenging activities,like doing the same practice in roadways buses.
