I know exactly what you mean regarding the age thing dude, definitely. Like when I speak to my youngest brother who is 8 or 9, can't remember which, lmao ;_; my bad, I don't stutter much if at-all. I think everyone is different, we all have different ways we stutter, different levels of severity and what not and yeah man, I tell no-one either, most people are shocked. "What? you stutter? since when" and all that shit, but I hope it getrs better for you around your dad man, maybe with time or whatever it'll get easier, but I'm the same for the most part man!
