Dear Prudence,
About four years ago, my brother lived with us while he was between jobs. He was involved with a local girl named “Lisa,” whom I never met, and he ended it abruptly. Later he told me that she had never told him she was married, and that he broke it off with her when he found out. My sons are in preschool now and there is a little boy there who looks exactly like them—dark curly hair, dimples, the works—and whose mother is a blond, blue-eyed woman named Lisa. I spoke with her a few times and learned that her son’s birthday falls within the time she was dating my brother. I looked up her husband online and found out he is much older and also has blue eyes and light hair. I would chalk it up to coincidence, but this boy looks exactly like my sons—it’s eerie. I snapped a few pictures of Lisa and her sons and now I don’t know what to do. My brother lives in another state, and I know he would want to know if he had a son, but it feels like I have a live grenade in my hands. Should I send the pictures to my brother? Mention my brother to Lisa and see if she reacts? I haven’t even told my husband yet.
