This summer, Dad and Mom came up for a long visit, so Dad could do some work while he was here. They arrived in early May, and were initially expecting to stay in a house, but plans changed and they stayed with us. Towards the end of June, they had an opportunity to housesit for parents of friends of ours, and then Dad flew Mom home so she could spend the rest of the summer in her own house. Dad came back in early July.
