This is the card I made for my Mom's birthday this year. When my brothers and I were growing up, we'd be like, ooh lets go and get some ice cream and she'd say "let's not an say we did."
Not all the time of course, we did get to do things, but she liked to say this on occassion when she wasn't going to let us and it just seemed to me a particularly awful thing to say.
But now when I think back over my life I realize that was my mom having fun, making a no into a more fun way of saying no. And that is very much my mom. She's always had a way of lightening the mood about things and its one of the many things I really appreciate about her today.
