Is it kind?
Some times the truth is not kind. I'm not saying to be intentionally cruel but the truth does often hurt as it rubs up against the little lies people tell themselves to avoid the painful aspects of personal growth.
Is it true?
As above, the truth is often not kind. So many things that are kind are not true and many things that are true and not kind.
Is social media the place to present these?
That is another question all together.
Is it necessary?
Nothing (well, 99.9%) of the posts on social media are not necessary. Most people are here to distract themselves from the world of personal experience (myself included) around them.
