I usually had joint birthday parties with my uncle because we share the same birthday. Of course, my parents were divorced so we did birthdays twice. I think the most memorable for me was one at my dad's house because my mom (stepmom) made me a cake that was right out of a magazine. It was so cool! It looked like a little windowbox filled with flowers.
On my mom's side, I had my 15th birthday at a skating rink and that was fun because all my friends came.
