What’s your travel style: serendipity or advance planning?

I also have written lists I go through. It includes “chargers”. But- last shorter trip, while I got out H’s travel kit I did not put his razor charger in. He now knows wife does not do EVERYTHING for him, just most of it. It is useful to have one compulsive person. The advice “you can just buy it there” could mean how many umbrellas, how many OTC meds… in your house.
