Facebook means never having to say goodbye. The social media web site has earned a reputation for reconnecting old friends. Last week, a guy whom I hadn't seen since my bachelor party five years ago sent me a friend request. I accepted and waited for him to send me a greeting of some kind. He had sought me out, after all.

I learned from his profile that he was in a relationship and had a son. However, I'm pretty sure we won’t ever write wall-to-wall, let alone e-mail each other. But he'll remain a friend of online until one of us makes a point of removing the other from his official list.

My pool of friends consists of family members, college buddies, co-workers from past and present, and friends of friends. There are 35 in all. If I spent some time uploading old e-mail addresses, I'm confident that I could increase my friend count actually.

A person could make a mission out of reconnecting with childhood friends, former classmates, distant cousins, and those one would like to get to know better. And some people can even handle hundreds of on-screen relationships, keeping up with the daily happenings of their small army of companions. After all, there are worse fates than having too many friends.

Thanks to e-mail, the inability to schedule face-to-face meetings no longer means a friendship must come to a close. But even with e-mail, people will lose touch if one or both parties stop writing back. That's normal. People move from school to school, job to job, city to city. You never have to feel guilty for breaking away.

Every day, the masterminds of Web 2. 0 find new ways of making human communication easier. However, convenience can be a crutch. Some things shouldn't be simplified. When it comes to friendship, there can be no shortcuts.
