Last week I visited my elderly mother. She needed to attend a medical appointment two hours away, and my sister who lives close to her was away. Last night, we visited my parents-in-law for Father's Day. We took them a meal they like but don't normally buy for themselves, and I baked a chocolate cake. (Twice, actually, but you don't really need to know that I threw the first one on the floor, as it slipped out of my hands getting it out of the oven!) My mother-in-law commented that we are "the only people they have." Practically, she is correct, as her other three sons and daughters-in-law, and seven grandchildren, all live overseas.
Don't ever tell me that the childless are selfish, when so many of us nurture and care for those who need it, without question, with love and support and generosity and thought.
