Dear Amy: Two years ago (prior to the pandemic), my husband and I went on a cruise with longtime friends. They then asked us to join them again. The date is approaching, and we are having a huge problem letting my sister know we are going. I know this is a first-world problem, but my sister is a widow and counts on us to provide her with all her socialization. My husband has been a saint in making her a part of all our vacations, dinners out, etc., with no complaint.
