You can hear what they're saying. Maybe they don't even sweat you enough to hide their disdain, their disrespect.
And it just kills you. Them talking so bad about you.
But do they really know you?
Do they know your capacities?
It might be, you've learned something, read something, or experienced something that puts you far ahead of just some neat derogatory(bad) label, like hash tags or something, trying to define a life.
And they nay-sayers might not know at all, and yet, they continue to sling verbal mud or your name.
