Feeling connected no matter how small is a very strong force. I like that I have connections from my childhood to my present and to all the places I lived. Even if it is I see that my friends kids are now in high school or that someone had a great event that I had zero impact on them having.
When my son was dying from cancer I just had to jump on Facebook and I had a ton of people that were willing to help out or send him messages and videos. It was a great tool to find people who could help.
