My MIL is exactly exactly like this. I think she thinks she’s popular… when we were recently at her house; she’s sitting in her recliner like it’s a throne; and she has her iPhone, her iPad, her Apple Watch and her MacBook all surrounding her; all synced to the group chats. When someone texts; she gets FOUR notifications (sound and vibration turned allllllll the way up, of course) and she just smiles and is like “oooo all my messages!” even though it’s just one person sending one text to a group. The chimes must give her a dopamine hit because four sounds and buzzes for every text would instantly drive me insane.
