This is to the person who stole by personalized parking sign, "Reserved for Grandma." It upsets me that you would take something that was not yours, and was not meant for you.
I bought it for my mother, who had difficulty walking, and therefore we could park in front of my house.
My mother (97 years) passed away in December, so maybe you thought I didn't need the sign anymore. But I would still like to have it.
It always reminded my family: "Don't park there, it's for grandma."
Maybe if you don't really need it, you will bring it back. Just come in the middle of the night (like you did before) and put it back.
That would be nice of you.
