how did my mom forget

how old my brother will be this year. i know a lot is going on around her right now with her brother getting to go home from rehabing a broken hip and her son and grandkids moving in but really. last year we were planning a double 40th party for my brother and sister in law. how soon we forget. i must admit that i had a rolling on the floor laughing my butt off moment when I realised she had forgotten. i also have been gleefully rubbing it in as well. (i klnow i am so mean) :) so in case i don't post between now and then happy birthday little brother.
