Un-

Unfollow.
Unfriend.

When we were kids, for whatever trivial reasons,
"unfollow" and "unfriend" already existed.
A much more direct approach of "I don't want to friend you".

Sometimes you get what's coming to you.
More often than not, you don't know what you've done.

Hurts none the less.

Admittedly, we all have been the clicker of the "unfriend" and "unfollow" button,
for reasons that are our own.

Maybe the other person won't care.
Maybe they hurt like you.

For what it's worth, I apologize-
As the clicker of the button.
As the person who may have done something to merit the clicking of that button.
