I couldn't find a Torah quote that is appropriate to this theme (any suggestions?).
I remember my parents signing my reading homework as required by our teachers. My parents signed notes explaining my absence from school. I occasionally forged my parent's signature when I chose to be absent from school.
I signed leases and home ownership deeds. I signed contracts for jobs. I signed checks for debts that needed to be paid. I signed the back of my credit card.
My University diploma is signed by the Dean of the Science Department. Our portrait is signed by our aunt.
Each signature is a work of art. There is a whole science around looking at the loops and lines of a signature and what it reveals about your personality. I wonder what my messy signature says about me.
