Likewise, when I'm around people who are smoking pot, they usually have a really hard time accepting it when I politely decline to partake. In fact, this holds true in almost any situation where people are consuming a thing that one doesn't want to consume. (I've had people try to make me agree to eat smoked fish even after I've explained it makes me queasy.) And it goes way beyond this, when you come down to it. Look how outraged fans can become when faced with someone who doesn't share the same enthusiasm. What it amounts to is that people generally don't like it when anyone doesn't agree with them, be it about food, drink, music, books, politics, or religion. It's that basic streak of douchery (or diquishness, if you prefer) that resides within us all and that we all must struggle to overcome.
And that's my simple-minded Christmas message. Ho ho ho!
