So Easter is long over, but something occurred during Easter that I was quite happy about--but wasn't sure if there may have been a different meaning to what happened.
The backgound: So my brother and I are firm atheists, with my brother being quite a bit more outspoken than I. Our mother is moderately religious, but not too serious. We had some extended family over, however, who is pretty close to evangelical--my aunt, her daughter-in-law, and two kids came for Easter. My aunt is very religious, but not quite as bad as her daughter in law. This woman has absolutely NO respect for other beliefs: she's a complete bigot like one you would see in the news.
Anyway, so since it was Easter (and my brother and I only "celebrate" it because we like visiting our relatives) and during our lunch, there was no prayer. I thought for sure there would be a prayer, but there was not. Granted, we were not sitting around a table--it was a "dish up your food and sit where you want in the living room" type of thing. But still, I (and my brother) were shocked that people this religious didn't do a prayer (or at least announce it).
I am skeptical, however, that this was done out of respect (on the daughter-in-law's part at least). Are there any other potential reasons for this occurrence? Or was it truly polite?
