I agree that "don't want" is miles better than "can't have", both for how it makes us feel,
and for how others react. The former is a nice, assertive statement.
Have you ever noticed that the minute someone says they can't eat a particular food item, other people are on it like a ton of bricks? "What do you mean you can't?", or "A little bit won't hurt."
Glad you're enjoying the WOL. I am too!
