Even though a person may have hundreds of Facebook friends that he or she doesn’t regularly interact with on- or offline, just knowing that the network exists in a somewhat tangible form (catalogued on Facebook) can be comforting.
Since leaving the Navy, my social media acts precisely as this kind of dormant network. I have hundreds of former shipmates catalogued on my friends list whom I rarely speak to anymore, but it is highly comforting to know those connections are still there if I ever need to reach out. It is a great way to preserve those intense bonds formed during six and a half years of service without the pressure of constant, daily communication.
