Police spotting (junction watch)

Does that make it ok to make digs at other people then?

That depends. Shouting "you're a fatty fat fat" at some random person isn't really on, but spreading the attitude that being overweight is unhealthy, and therefore is a bad thing, (and the same goes for underweight) is generally a positive thing in my book.

I'm not saying I would say it directly to anyone (I'm generally too polite to make personal comments), but it worked for me.

So how do you know if the fat copperess, for example, has a gladular issue or not until after you insult her? Psychic ability?

I don't, and as above, I wouldn't say anything in the first place.
