Just had a conversation with my DM that her and DF are disappointed that my DC’s (11 and 13) do not contact them or message them directly.
They do not contact my DC’s and it has never really occurred to me to encourage DC’s to.
They see them sporadically. Very much one way in that we usually always visit them. They are both retired. Live about 30 minutes drive away. Both very active but rarely choose to visit us.
