What happens at the India - Pakistan border?

India, Amristar: I went to see the India - Pakistan border called Wagah border. At the Wagah-Attari border ceremony, India and Pakistan share a peaceful moment inside a stadium that is divided into two sections, one in India, and one in Pakistan. The celebration consists of the army opening the gates, music, and partying, which is surprising cause currently, the two countries don't have a good relationship with each other.
