For reasons I will not go into, we need to watch Trinity and her younger brother for the day, unexpected change of plans. That's what family does for each other, we stand with you and hold you up when things get complicated. That's what love is. Family that choose us has a stronger bond than our biological family; sometimes.
We are always enriched when we watch our 'grandchildren' but we have concurred with the old adage, "God knows what he is doing when he gives the younger generation children."
At the end of the day, we will be tired, but very happy and have learned something that our grandchildren have taught us.
