He said i m missing You, give me a hand. It was hardwarming but on the other hand also painfull they were separated.Meanwhile we came to know from the nurses that dad has a serious infection which is life threatening. They gave him antibiotics and fluid by perfusion. They still don t know from where the infection comes. Dad has also lots of backpain. Next week he will undergo mri scanning so they can see the cause. Meanwhile sister and i are alternately sleeping and staying with mom. sjhe can t stay alone as her eye sight isn t that good.
