Oh Tabris, you are of my mindset. Once, about four years ago, my clan went on Christmas morning. I loved it! The youngest in our family is 31. Obviously, Santa isn't a big concern. We have always opened our presents on Christmas Eve, so, once again, Christmas morn is available. Oh, how I long for the half empty seats! Oh, how I long for the 'good' parking spaces!
This year, we went to the vigil. It was packed. We ended up in the third row. (No one likes to sit up front.) We were lucky to have seats -- we only got there 30 minutes early!
But back to the topic at hand... were there ushers available? I would have evicted that family. (I realize that goes against the inclusive nature of Christmas.) If there wasn't a children's room (one of those glassed in, sound proof areas that people can see the action, hear the piped in service but from which cries can't be heard), they should have been sent to whatever hall facility existed. The only food or drink in church, aside from the bread and wine, should be bottles, maybe some Cheerios, and hard candies for the occasional Diabetic.
