Granddads Wish

Before i get into anything this is all new to me i have never asked for anything in my life but me and my partner are struggling to get things done in time we have so much towards our wedding but  are short. It started with being brought up by nan n grandad so they more like me parents and he has been diagnosed with parkinsons he has got to the point where he can hardly walk and hardley stand it hurts to see him like this as we have to do most things for him and he is only going to get worse and by the end of it he wont even recognise any of us and with the fact he brought me up from the age of 5 i really want him at my wedding.
