A familiar little search
The trip is coming up.
The adapter is somewhere at home.
A work trip is coming up. You open the cable drawer, move a few things around, and pull out the wrong cable. The adapter’s location has slipped from memory.
Then comes a small change. Before putting it away, take a photo and record the drawer.
Next time a work trip comes around, search your saved records for the adapter. Its location points back to the tall cabinet in the study, third drawer. You have a place to look.
