There's also a second important distinction between ano and kono when talking about things like memories and events.

Suppose you are talking about a vacation you went on. If the addressee went with you, you would say "ano tabi," but if the person didn't go with you, you would say "sono tabi."

Basically, the default is "sono," but if the addressee and you share a "bond" over the memory, use "ano" instead. The rule applies for sore/are as well.

Please chime in if I got so/a switched here, but as I've been doing it this way for half a decade now, I'm fairly sure I'm correct.
