Friendship is a complex topic. And a difficult one for many people, me included.
After I was disabled by a stroke, nearly 8 years ago, at least half the people who I thought of as friends never contacted me again.
I've been told that's not really unusual.

I had an episode on my YouTube channel not long ago, about some different kinds of friendships.

If you are a good friend, don't change. It will be rewarded.
