No need to be sorry. I love learning the ways and customs of others.
My son is "home." Not with us. He lives in Chicago with 3 other students.
One of the things I didn't mention about Christmas is that we have to visit both my family and my wife's family. We don't try and do it on the same day so we often get together on one of the Saturdays before or after Christmas.
Christmas ends up taking a couple of weeks.
