Definitely spa day! Also, does she work outside the home? If so, here's an idea for you! When a friend turned 50, we printed a handicapped sign on the computer (8X10) had it laminated and mounted on a yard stick then took it to her office and put it in the ground in front of her car. She got a basket full of hemorrhoid cream, denture cleanser, geritol, the little eyeglasses you get at WalMart, a foldup cane, shawl, well - you get my drift.
I'm just glad she didn't hold it over my head when I turned 50 in August
