Your response was okay. Christmas Eve is a month away and things can change between now and then. So, I would sit quietly and wait to see what transpires. If your sons want to keep to family traditions, they can advise their father of their wishes in December.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
