My own mother forgot I have a hearing aid and hearing loss when I told her that I found out last week that my hearing loss has progressed she suddenly looks shocked and hurt as far this is the first time telling her. I just shook my head and sighed.
Family is funny that way..
One Christmas I got a small travel alarm clock (as in the spring I and a few others from school were going to Italy, aunt was a chaperone)...from my aunt. I looked at it..looked at her. Said.. Um.. you do realize I'm not going to be able to HEAR this you know...? "Oh! Oops.. I forget sometimes"...yeaaah... lol. She took it and used it for herself lol; my sibling also got one as we both were going.
They're not as forgetful now but it still happens...
