Even while putting together a million piece bunkbed? You simply mention grandbabies....and then that's all he can think about. Grandbabies sleeping end to end on his carefully assembled bunkbed. Then he forgets about his knees popping out of joint from kneeling all day. And about his aching back as he bends over for hours on end. Yup. The magic word around here is GRANDBABIES. It makes everything a labor of pure LOVE.
