Yeah for real. Some days it's really bad and 1 out of 10 times you find yourself speaking completely normally in a situation where you otherwise would have blocked. Goes to show how there's probably an unconscious part of stuttering we don't know about, but we all have the potential for fluency. Being comfortable and confident in a situation definitely helps as well, but for some reason I stutter in front of my parents the most for no reason whatsoever.
