I definitely would pick same weekend if i were you. Moments like that with family, celebrating parents are always cherished. All of that laughter and dancing and eating amidst bonding ia very wholesome. I know how very perfect it is. I do.
And, I also hope, as you do, that your father gets to live for longer and in good health too.
So beautiful! Thank you so much for those wishes that convey sincerity. Those hugs are worth gold, being able to reunite siblings and remember our childhood is of great value
