I realize that it's not only me. I've seen many other guys who are about the same age as me, react in a similar way. On a more serious note, of course, all of us accept that we're getting older. In fact, we rarely bother about it (We're not that old, yet). But on a lighter vein, hearing someone introduce us as an 'uncle' give a slight prick :) One of my friends has taken to signing his name as 'Youth' in his personal mails to friends :)
Nowadays, age (or 'youthfulness') is a regular way of teasing others. The younger guys in our group will call themselves 'kids' and tease the older ones as grandpas, while the older guys will pretend that the younger ones are not old 'enough' to understand certain things :). But as soon as a guy marries, this equation will automatically change. He will then become the 'Big uncle' or the 'Grandpa' of the group, even if he is much younger than the rest of us.
We are going through a transitional period of our lives - We're getting older and moving out of the college (or fresh out of college) mentality; settling down in our respective careers; seeing so many fresh baby faces around in our workplace (against whom we seem older); hairlines receding (this is a very important one); and slowly each one is entering into marital relationships. I guess, all these are making us want to hold on to the image of "youth", a little longer.
I would like to revisit this post when I make the next transition - from being an 'Uncle' to a 'Thatha' / 'Grandpa'. I wonder how it'll be then :)
