Whoever does not have are son at nite calls around 8:30 to say goodnite and all that stuff. Well I was on the phone with her and son picked up other line, she knew we were both on the line.
My son while talking with both of us asks his mom,

S- "When you and daddy live together again, can "dog" live with all of us."

W- "Yes, "dog" will live with all of us too, the cats miss him."

Dog lives with me, she has the cats
