A rain delay pauses the game. Nobody packs up the stadium over it.

Interruption is not cancellation, though the two feel identical while you are standing around waiting. A pause in something you care about tends to trigger the fear that it is over, because uncertainty is harder to sit in than bad news. Most delays turn out to be delays. The structure around you is still there and still intended to continue.

During a stall, do the small maintenance you would not otherwise have made time for. Stay warm instead of packing up. Being ready when it resumes is the entire job of a delay.
