I have a buddy, He and I have known each other for 22 years. We were classmates in univercity. After graduation, we live 100km away. I got married, He got married, and he had two daughters. We made efforts to keep in touch with each other, we possibly met once or twice a year, but what connects us so tight and so long was internet. We made a correspondence site in 2000 and it still lives. We conceived of an idea that making an e-book from the site and we did it. To celebrate its publication, I biked to meet him for 100km.
It's not impossible distance to bike but not so easy distance. However, it's very very shorter than the distance between you - now reading this somewhere on Earth - and I. Internet even helps him and me who live nearby.
