Why compartmentalize your love? I recently attended a funeral and shared sympathies with several strangers that over the course of time, became closer to friends.
Your friend almost certainly loved their family, and their family loved your friend. Although they may be gone, you can still keep that connective love alive by doing the same things for others that you’d do for your friend - sometimes, it’s as simple as showing up, even just once, for someone else.
Do you really have to fake that?
Yes, I dont connect over these things. Also I have a pretty good circle of friends and dont need more people in my life. Every loss of a friend is like the world os falling apart and with more people in my life id have to go through that even more. I keep the number of people I have to deal with small.
