robin ( my son ) and emma ( his wife ) had already provided mark ( my first grandchild ) with a sister , ( macey ) , and it was work in progress for yet more , but as we watched the sun slowly disappear below the horizon i yet again reflected on the fact that the money was handy , and it gave our children unheard-of security , but i know that the three of us would give it all up in a flash to have sheila ( their mother ) back .
