Dear Annie: My husband and I have been married for over 20 years. When we met, we had both already lost our parents. During all our time together, my husband’s younger brother has spent Christmas at our home — even after we got married and he got married, after we moved out of state and had children (now 17 and 20), and after he and his wife had their child (10 years old).

A few years ago, they decided to stay at an Airbnb for Christmas for several reasons, including visiting other family and friends in our mutual hometown. However, they spend a portion of every day of their stay, which can range from five to seven days, with us, and of course, they spend all of Christmas Day, including Christmas morning, at our home. They don’t even ask; they simply inform us what days they’re getting in and leaving.
