After my husband died very suddenly in the New Year, my daughter, whilst coping with her own grief, was very aware that our 7 year old grandson might ask some questions to which there is no answer. The evening after he died there was a particularly bright star in the sky, so she drew his attention to it (he is very into astronomy ) and said 'Thats Grandad's star. Whenever you see it, you'll know he's here, looking down on us'. Image my surprise, or actually my momentary alarm , when I was staying with them at Easter, and he quite calmly announced ...'Grandad's back'. The star had of course appeared again in the small corner window that he and my daughter had first seen it. It gave us a bit of a turn, but he had remembered what his mum had said, and while it may seem mawkish, and totally without human logic, it reassures him for the time being. Obviously when he is an adult he will be able to ponder life, death and the million ways we imagine our mortality or immortality.
