I think i have a good one.
One time i was at a friends house and his girlfriend asked me how old i am.
In those days , i was 21 at the time , i didn`t waste a single thought on my age. Never ever.
I had to calculate back the difference to my year of birth to come up with an answer.
She must have thought that i`m totally stupid.
That was embarassing , but actualy to myself i thought "why should i give a damn".
Kind of like a new intellectual approach to the subject.
For me , she was strange , worrying about time and age.
