"You have been selected to be one of the seven students to light the Christmas trees (in the church attached to the school). You were selected because your birthday falls on or nearest Christmas. Often your birthday celebrations maybe have been overshadowed by Christmas. We would like to honor those who share their birth-date with Our Lord's."
We try hard to make sure Middle Sister gets plenty of "happy birthday" treatment in the middle of Christmas celebrations, as her birthday is the 27th.
I think this celebration at school is a really sweet idea.
