Transitions of thoughts with age

It's bemusing how one's thought and views changes as he or she matures.

I used to hate it when people smoke, and if they're my friends, I'll keep reminding them to smoke less and encourage them to quit.

But now, as much as i dislike people to smoke, I sort of understand how hard it is to quit, with the cold withdrawal symptoms and stuff...Not that i have been through it or sorts..haha! But i don't detest smokers as much as i did, younger!
