It’s not just that I have a quiet voice (which I do), but it actively hurts to yell. Like I’ll shout something for 10 seconds and my throat is sore for the next week.
My dad is an excellent yeller, and my mom can project her voice quite well. That’s not me insulting them, I’m saying that because I don’t get how both of my parents have expressive voices while I don’t. My siblings have pretty loud voices as well (except my older sister).
I don’t need to yell. In fact, I think most people don’t need to. But when I’m in an area with lots of people talking, it’s hard to speak to the guy next to me because he can’t hear what I’m saying half the time.
