I went round my parents house the other day, and they had the TV up SO LOUD!!!! Literally it was hurting my ear drums. I pointed this out to them, and they hadn't even noticed. So their hearing is on the fritz.
They don't need glasses for everyday living, but for anything requiring reading, they do. Not just reading but anything that requires close attention. Then, they can't find their glasses, and spend about half an hour tracking down a pair, which only have one arm, and a dodgy chain so they can put them around their neck. Eyesight going.
My mum talks to herself. She claims she's talking to the parrots or the dogs, but she's not. Why? Because they're full blown conversations and, at times, arguments with herself. Mind going. (My Dad lost his mind years ago having to put up with my mum...)
So, how do I know I'm getting older? By moaning about my parents getting old!
