Why are birthdays not as much fun anymore????

Things are getting back to normal around here. My sister went home, the kids and granddogs have went home and I survived another birthday. Why is it that birthdays are not as much fun anymore??? lol! In all the excitement of having the kids and granddogs here over the weekend, I have hurt my knee again...so no aquasize for awhile...I am hobbling around again! Ugh! I am not good with pain! Take Care and God Bless! Donna
