Well I took my Mother for a hearing test today. She told the guy she had no problems with her hearing whatsoever but came away with a pair of hearing aids!!
HE was very patient with her when he told her to listen and when she heard a sound to press and release the buzzer. She kept pressing and NOT releasing. After not getting anywhere he removed the buzzer and said she was to listen for a sound and when she heard it, however faint it was, to just say "Yes".
bless her heart, she couldn't do that either and kept saying "I can hear it but it's very faint" or "Yes I can hear a different sound" he kept saying "just say yes" and it was actually quite funny.
She wore them coming home and we sat in the car outside the supermarket and she nearly jumped out of her seat when someone pushed their metal trolley into the others.
WE got back to hers and I went to the loo and she calling "quick, come here quick." I ran into the kitchen and she's standing looking bewildered. "There's something going on in here, listen. It's like something is stuck somewhere and it's scratching to get out." After much investigation it turned out to be her big wall clock which she swears she's never heard ticking before. We had a good laugh!
