Dear Annie: My sister expects me to make my son and his friends spend time with her son. Our sons are in their early 20s and used to spend a lot of time together when they were younger. Her son, whom I love very much, is on the autism spectrum and had some emotional regulation issues as a child and teenager. Now, as a young adult, he has much better control over these issues, but sadly, his peers have not fully recognized this and often exclude him. Her anger has led to her texting me some unkind messages on more than one occasion.
