Oh wow sorry to read this, I just would like to say Happy Father's Day to you (here in Spain it is not in June but I have seen in many other countries it is now), but I understand that it was not the best day for celebrating, but you did what you had to do, your role clearly but obviously the disappointment feeling was present. I hope the incident will be solved easily and that event should be a lesson for your son, my best wishes.
P.S. I understand well when a celebration become a non-celebration anymore for something that other person does or similar... breathe and wish next time that day will be better, amigo 😘
