On Monday morning, I followed the custom of my friends and left my tefillin bag at shul in the aron hakodesh (holy ark).
I walked home feeling anxious. What if I got up in the morning and did not want to go to shul to put in tefillin? What if I just wanted to do it at home? Or what if something came up and I needed to daven shacharit (morning prayers) somewhere else? Or what if someone stole my tefillin (they cost me about $500)?
The next morning, I took my tefillin home again.
