(spoiler alert! for those who haven't seen this weeks episode)
I found it kinda dumb that the girl who started talking to emmet didn't just text out what she was saying when he let her know he was deaf. She is supposed to be dumb, i get that. Is that a common reaction though? To apologize and then just walk away? It's not like he doesn't know english, just text what you were saying and apologize for not seeing that the person was deaf (not bc they are deaf).
