I hate to admit it but yes I am of an age where I can legitimately say that. I have been (un)fortunate enough this past year to work with a lot of early 20something people and have been quite taken aback at their attitude. The over confidence and the "Why can't I do what you do?" attitude. It is a huge generalisation and of course it is always just a few rotten apples that spoil the whole bunch.
Was it the same when I was that age? Maybe I was that cocky kid once upon a time too.
I overheard a young couple on what I think may have been their first date in a restaurant this week.
28 is apparently "SO old", and this young med student didn't understand why doctors look like they do (ie tired). She believed that doctors should look better than everyone else. WTF?! All I could think was - she has no idea what a hard days work is does she. Then I put a few other clues together - Bondi, comes from money, Jewish - she hasn't done a hard days work in her short short life ever!!!
And then there are times the younger generation come through and really surprise me.
I'd like to tell you how proud I am of my niece and how honoured I feel to have been an influence in her life. I love being an aunt and it could be all I have if I never get around to having kids of my own.

They did find some time to shop - as all good teenage girls should. She bargained with market stall owners on jewellery and souvenirs. She happily wore what she could tonight at dinner and brought presents for her grandparents and 3 younger nephews. She was not prompted by anyone to do this, just did it because she wanted to. And that impressed me too.
