Exactly!
With that clever coupling trick you made sure that if one thing happens, another thing happens as well. I don't have that sort of connection to my lunch box, and I've paid for it many times. Probably should develop some sort of routine for that as well. So far, I just hope that I remember to do everything in the morning.

As long as the sequence of actions isn't altered, it works pretty well. When something unexpected happens and I have to deviate from my routine, that's when everything goes off the rails.
