I heard a story this morning (in worship, no less) that drove the importance of "sabbath" home to me. Evidently, a woman who works in the high-tech industry here in Silicon Valley was talking to her boss at 2:00 in the morning while breast-feeding her child, and when she announced that she had to hang up because she had to put her child to bed, her boss responded, "That's okay. Call me when you're done."
Attitudes such as this is why we need church (or synagogue, temple, mosque). We need a place or community to remind us that just because there are some in our midst who worship 80 hour work weeks, we don't have to.
