I look at my In Laws NCB, they are in their 70’s, still hold hands, leave notes for each other, send each other texts, seem so in tune with each other, finish each others sentences and seem to delight in each others company, its truly heart warming to see, they do seem to be soul mates……. I think its rare but yes its out there….. but don’t look for it….. it will find you …. and if its not reciprocated then its not the right person :)
