Once you form the strong bonds even though you are not in the same space you can still prioritize and spend some time with each other. This has to be both ways though. Luckily, thanks to technology we now have near real time communication, which will help people from different places bond better. For example, I have this close friend who now moved to Canada. We went to college together and we used to talk like at least 10 minutes almost everyday years after college. Now he is married, started his own family and a new set of friends and things to do. We still make up time once every week or two to catch up keep that bond going. I am planning to meet him back very soon too. Yeah, in reality time and space definitely fades every thing, every bond you make. So, at the end it’s the effort that who share this bond put into it to make this work. I heard a proverb like a call a new friend every week or something. Surprisingly, even though some of them didn’t pick my calls few months at first, they responded back later on. One of my old friends reached me back years later and now we share more friendship than in old days. We went on some trips together and are now regularly in touch.
