My aunt would always say "hezky den" when saying goodbye on the phone - was she meaning, more literally, "have a nice [weather-wise] day" rather than "have an agreeable/pleasant feeling" day? The usage in phrases like "to je hezke mesto" makes sense, but the meaning in "hezky den" confused me - perhaps this isn't as universal of an expression, or just another one of my aunt's quirks...?
