does she like big surprise parties? Big not-surprised parties? Trips abroad?
A pork scratching quiche sideloaded with black pudding.
Failing that, something nice - balloons, flowers, homemade cake and a trip to the bowling alley.
Failing even that - skydiving wargaming. Though she might need to grow a ginger pony tail to fit in if the clientele of our local Games Workshop are anything to go by.
Weight gain, grey hair, sagging tits and the menopause ;-)
I've got all that except the last part.
Well I was going to plan a nice party for her with her friends, and keep it a surprise, but I've been informed that her girl friends are taking her somewhere. :-S
