They say that nothing is permanent in today's world. But they're wrong. Things come and go, you witness ups and downs, relationships begin and end, but there is one thing that stays just the same: our old friends. They've seen us transform from bratty kids to grown up professionals and even if we don't meet them often, they make our lives better just by being a part of it. But very often, we get too busy or are just plain lazy, and end up losing touch with them. However, it's never too late to pick up the phone and make a plan. Here are 11 reasons that will make you call your old friends:

laugh together at embarrassing memories.

Remember that time when we were caught eating food in class? Or that time when we were punished and we giggled standing outside the class? You get to revisit so many such memories, smiling and thinking of how silly you used to be.

To reconnect with our roots.

Life is a roller coaster ride. Often, it gets to us, and we forget where we've come from. But old friends ensure that we stay connected with our roots.
