You and your partner, both widowed, have adult children and grandchildren. You don't live together but get together on weekends for outings. His daughter has a habit of contacting him when she knows he is with you. You find her intrusions inconsiderate, rude and annoying - both on her part and his - because he invariably responds immediately. You would have no problem with matters of importance but you're utterly fed up with their texting about trivial things. You want to know how can you put an end to it?
