Quote - I wonder why it is that if you do things that show you're content and happy it's frowned upon?

Well, in my case it's because I live in England. The House of Lords is currently debating a bill to outlaw displays of emotion in public places. In my village, if you try to make a joke with the (very sweet) girl in the pharmacy, the smile police jump out from behind the counter and drag you away for a beating.
