Will try to keep this fairly short.
My friend's mother died recently. Friend has three adult children. Friend and children's father are divorced, both remarried. One child with her partner, the other two currently live with their father, as they work close to where he lives.
All three children attended the funeral. Friend's ex did not. Friend's ex lent one child his vehicle to enable them to the funeral.
After the funeral, at the wake, child who does not live with the father gets a text, "What are you up to today? Wondered if you were coming to us for Christmas?"
Just wondering what response would be appropriate.
