How not to pack for a trip

Slightly less useful for packing than you'd think

What I managed to do in the half day of preparation time I had before my flight to Miyazaki:
Make the bed (off to a good start!)
Take everything out of the closet and lay it out carefully on the bed (a sensible and necessary precondition to packing for a casual weeklong trip)
Cull a few old clothes for disposal, decide to think about optimal arrangement for everything else
Go to Irukaya for a glass of rich iced coffee shaken with lemon and cream
Have a second intense demitasse of coffee
Run back home
Snap a photo of a gigantic plate with a white ceramic gun fused to it that was left out for trash
Send detailed instructions to a friend for retrieving said plate/gun 
Stuff everything back into closet
Turn off the gas (this is a thing— earthquakes)
Chuck a lot of things, mostly for summer, into a suitcase

What I did not manage to do:
Put container of week-old vegetable soup into the freezer or trash
Ditto already overripe avocado
Ditto half carton of milk (free pass — Japanese milk doesn't spoil)
Research travel destination
Ask friends in Miyazaki if it would be okay to stay with them
Eat
Check weather forecast
Pack any socks
