Next time you complain about going to school (or hear someone complain about going to school), take a look at this.
Seen here are Rajesh Kumar Sharma and Laxmi Chandra and together, they run a free school for children living in the slums of New Delhi, India under a metro bridge. Around 30 underprivileged children attend the school... the only school they can attend.
For two hours every weekday, Sharma leaves his day-job at a general store in Shakarpur -- his brother fills in for him -- so that he can teach the children. Sharma was forced to drop out of college because of financial difficulties and did not wish to see an education denied to children just because they are poor.
