Social media feeds often make it feel like we are the owners of the space we comment in, instead we need to remember that they are merely windows or doors into the lives of others.
When we reply without pause to think we wind up making our response more important than the person.
Is that blunt comment really helping?
Is that joke really funny?
There are shared spaces where we all expect the unexpected. It is a very different thing to go into a space maintained by an individual.
