Is it normal to not know what a consonant is?
I got an online friend, we were discussing names for our RP characters. I told her if she would like a character which name started with a vowel or with a CONSONANT. She asked me "What's a consonant?" I was speechless, I didn't know how to react since I thought that's something you learn in elementary school or earlier. She's 18, she goes to school, she got access to the internet, wtf?
