The promise!

On the last day of university the four of them vowed to stay in touch. They decided to meet at least once every year.

After a month they went to different cities for their bright future. But somehow they lost touch as they got busy in their respective lives. And forgot about the promise. Six years passed by still they never met.

We all have those friends from our high schools or universities, with whom we had so much fun. But unfortunately we lost touch and somehow never met .
