How Do I Stop My Future Mother in Law From Saying, I Am Deaf and Can't Verbally Communicate?

How do i stop my future mother in law from calling me her son's dummy boy friend? She always forgets that i lip read, so know exactly what she is saying. I would also like to tell her myself and my boy friend are in love, and it's not a phase he's going through. He's a fully paid up, card carrying, handbag swinging member of the pink party. What? He's not blind. God got. You are awfuli'm factual. Maybe cat o the bit out wher he was corrected. Well now, because thats you can still be deaf and literate. Oly olly, i love your letter, oh olly,
