I find 'you guys' annoying too. Have not been called 'dear' as yet, but don't mind if things are said in the right tone, friendly but not patronising.
If staff at the hospital ask what I would like to be called, then that's fine[it gives you a choice.] I agree with others that newspapers always seem to take a patronising tone regards older people, I also don't like the British thing of putting everybody's age e.g. 'Mrs Edna Tomson [36] said that the car had been speeding down the hill'. What the hell does it matter how old somebody is if they are merely a witness to something?
