Forgot the Mother-in-Law

As we were leaving Hobee's today after brunch, my mother-in-law said "I remember, I better get into this car quickly."  She was referring to the time we were getting into the car to go somewhere.  I got behind the wheel, put on my seat belt, and started driving.  My mother-in-law, who had polio as a child and sometimes walks with a cane, was sitting on the back seat, door open, slow leg still on the ground, while her cane flung in the air.  Oops.  Not my best son-in-law move.
