Following my first year in seminary, I did an overseas missions practicum in Calcutta, India. The six members of our group volunteered with the Missionaries of Charity, the order founded by Mother Teresa. We served in a variety of places, including a roadside health clinic and an orphanage. It was a life-changing summer. 

I remember visiting the orphanage one day. My wife was with me. One of the sisters met us at an outside gate. She chatted with us a bit before leading us into the grounds. 

While much about that day is lost to me, I remember one thing very well. As she was about to open the gate, the sister glanced at the ground. Then she quickly removed her sandal, bent over, and began beating it on the ground. It was only after she finished that we saw the snakes. Baby cobras, she called them. The sister had beaten them to death. Then she opened the gate and calmly continued our tour, as if killing baby cobras was no big deal.
