I speak to SIL (DH's sister) normally once a week on the phone, DS who is 21 will message his Auntie on his Birthday and Christmas to thank her for the card and money or present she has got him and he will also message her on her birthday to wish her a happy birthday and will always write her a card and give her a present for her Birthday and Christmas, apart from this he doesn't have any other contact with her, he'll never ring her or decide to visit her house by himself. Speaking to friend not that long ago and she was a bit surprised at the lack of contact DS has especially because he's an only child friend thought he would want to have stronger and closer bond with family members. AIBU to think this is normal contact for someone of DS age with his wider family?
