LOL I missed the "birthday" part in the original post! Sorry!
Sometimes when I see playing cards, I am reminded of my 17th birthday. My mom said I could have a friend over for dinner that night. It was a school night, so right after dinner (and cake and ice cream) my dad was going to drive her home. When we got home from school we were sitting on my bed playing cards, when Kim mentioned something (about her pjs or something) that made me realize that she thought she had been invited to spend the night. I excused myself and told my mom of the mix-up and asked her to not say anything to Kim, so as not to embarrass her. I also asked her to quietly say something to my dad when he got home, so that he wouldn't say something like, "So, are you ready for me to take you home?" It turned out to be a great birthday, and I had a friend to walk to school with the next morning.
