When I was younger, (25 years ago) I knew what exhaustion was.
Washing, cooking, ironing, shopping and keeping track of 15 kids, one husband, 2 dogs and two cats was challenging, I would fall into bed physically exhausted each night. I even remember falling asleep in mid conversation on several occasions.
I reckon its a bit the same preparing to go away….paperwork, notes, samples, double check and double check again.
It’s a bit far to come home for something you forgot.!!!!
