how should you react to it? - an occasion where you post a point of view on someone's video and you've posted quite a few times on this persons videos, but, he doesn't respond to you, or thumbs up your comment, or love it or give it any acknowledgment, but he loves, comments back, thumbs up and acknowledges everybody else's comment, but not yours.

how should you respond to that?
