Oh I loved that blog post Erin! Your story about the atm made me laugh because the same thing happened to me last week.
I long ago realised that little reminder (like "go down that aisle in the supermarket"!) was worth listening to. Sometimes it makes me laugh how seemingly trivial it can be, but its like a little secret compass that nudges me in the right direction.
It even happens to me when I'm adding salt to dishes when cooking (always sounds like my grandma) "THAT'S ENOUGH!" And when I pay attention, its always seasoned perfectly...
Gotta love it!
