Having too much reservation will do that to you.
Having so much to say but being sensitive to others may hinder your ability to actually say it. There you are, mouth swollen with things you want to give birth to, and you abort, you self abort, just for the greater good.
But there is no feeling good about an abortion, a part of you is dying after all.
Perhaps the withholding has a positive outcome if you can channel it. All my stillborns manifest into a calmer expression. Perhaps the patience allows a bit of simmering, a bit of editing before I release something incoherent.
It’s a nice way to deceive yourself, that being quiet is worth it.
