The other day I was driving across town when I realized that I'd left my phone and my wallet at home.
This has not happened to me in years. I was juggling a bunch of material and, in my rush, simply forgot.
I had the small wallet with my driving license and insurance cards but not the larger one with cash and credit cards. The jarring thing is I realized that if I were in an accident and had to borrow a phone, I don't know the phone numbers of family members. They're stored on my cellphone.
A small list of key numbers is now with my driver's license.
