That's funny how I find it cute when reading this... then I try to see myself as the man protagonist...
That's a nightmare. Try having a relationship with a girl that can't talk to you at all.
It's fine to us, because we see how cute she is with her inner dialogues, but he can't hear that. He just hears her mumbling five words per day to him.
What a boring relationship. Yes, she's cute, but so boring I would probably dumb her fast.
