Bob Greene: I would say the parish I'm currently in is maybe more extreme than I'm used to. Like Memorial Day, we're not mentioning it. Mother's Day? No. Just the liturgy is the liturgical. And it's almost like we don't pay any attention to what's going on in the world. That's the other kind of holidays. He says Thanksgiving is an easy connection because it's Eucharist, which means Thanksgiving. But you can think of some of the other significant days such as Martin Luther King Day and Arbor Day.
