There's something about childhood friends, no matter how many years pass or miles separate, you always pick up where you left off. Like you saw each other yesterday, reuniting with old friends always seems a little magical.
Those kinds of relationships can't be manufactured, they arise from years of doing life together. Countless shared experiences that create a rock foundation of friendship. It's hard to grow relationships like that later in life, but it's possible. Find people to do life with, and make deep, lasting relationships.
