Agism - the Final Prejudice
I have to say it's hard for me to understand why after 49 years using and programming computers, people think I'm a dinosaur just because I'm old. And female. (Some prejudices never seem to die.)
My "friends" ask complete idiots for help or information just because they're young and male. Then complain about the problems that result - to me. Sheesh! </grumpy>
