Reminds me of myself when my kids were young...I had a very stressful job & was always ripping and running from one thing to the next, dropping them off at school, ballet, picking them up, errands, trying to keep things balanced and everyone here knows that drill.
Anyway, at one point, I must not have been getting enough sleep or had extra pressure because I began to forget to close my front door when I left! This happened 2 or 3 times in the space of a week. I worked in a different city miles away and was mortified to keep returning home with kids to see my front door standing wide open. LUCKILY nothing was ever amiss and a "safe" area. So - I wrote a post-it to stick onto my steering wheel that said "Close the door" - except how embarrassing to be such a simpleton - so I wrote it in French "Fermez la porte". LOL. Clear sign one is overwhelmed...
