For me and my wife it’s a topic we bring up constantly throughout the year. Keep making suggestions and refining the ideas. Then October comes and of course he haven’t written anything down so we completely forget all our ideas.

Then two weeks before Halloween we say “ok we’re need to get costumes. It’s close”. Then we’ll come up with a very elaborate idea that we both know won’t happen, but we agree anyways.

Then 2 days before Halloween we check Amazon/spirit Halloween and do our best surprised Pikachu face when all the good costumes are gone or need more than 1 day to deliver and we end up settling on something dumb and get angry.

Repeat next year for some reason.
