I would definitely make my own birthday cake. As a matter of fact, I owe myself two b'day cakes now. Last year was the 4-0 but I was in the midst of packing up to move. This year, I was making a cake for someone else a couple of weeks back.
But, a wise friend counselled me - "You can ALWAYS have 'birthday cake day' whenever!" I think he just wants to be able to have cake to snarfle on!
But I agree.
I am busy on a b'day cake for my aunt's 70th b'day for next week and hopefully one to take w/me to New Orleans as a gift for my friends. So, "birthday cake day" will have to be bumped again...but by golly, it WILL happen!
