Birthday Cake Mice

My boss turns the big 50 this year!  I don't think he's overly traumatized by it --- and he shouldn't be, especially as he's entering the best part of his life with most of that pesky growing up behind him -- and I've pointed out I'll always be older than him, so how bad can it be?!?  I love these Miles and Maisie mice so am always happy to get to use them.
