I did not allow DS to take his own phone (as I wanted him to spend time w my dad vs. starting at it), but you are all right that I should have told my dad that I wanted to speak with my son when I called my dad to check in (I did ask if my son wanted to talk, but my son declined because he was watching tv; I should have insisted).
He's on vacation, having Grandpa time.
No, you should not insist to talk to him, and you certainly do not need to nag him about socks. Let it go. This is the minutia of life. Do not give it another thought.
