my husband and I went to my daughter's apartment again, for giving a plenty of foods. We heard her husband got COVID, too. I hope they survive. We dropped in at S.A, some road stations and a restaurant. We saw a rainbow appeared in the sky on our way home.
Oh, both of your daughter and her husband got infected! They must have a tough time. I hope they'll get well soon. The rainbow you saw tells everything will turn all right.
でも帰りに見た虹は希望の表れだと思います。
