Well, you can’t hear me so the comma helps and puts a little space in reading the same sentence, a momentary pause. I’m from Texas; I’m not a Cowboy (semi colon is used for a cause and effect sentence). Wow! That’s so cool! Exclamation marks add emphasis
I understand are you okay?
Sign language, writing/reading
Hope this helps!!
