I've been reading through the comments to the post below and have a few more thoughts to add.
The first thing is that we do the right thing because it's the right thing to do, not because we expect a reward. Not that any of you were insinuating anything, but it crossed my mind. I mean, we didn't waltz in there expecting applause. But neither did I expect such a cold reception.
Second, people DO need the Lord! We all surely do! Sadly a large percentage of folks in our area prefer a form of "spirituality" based on nature/environmentalism/new-agey-stuff/etc. to the truth.
I like animals. I like nature. I believe in being a good steward of God's creation. But I don't worship it. I don't elevate animals to equality with people.
Third, the irony is that while we missed out on learning a bit about the birds, it's the rehabilitation center that really missed an opportunity. While I'm not in a position to give them a monetary donation right now, as homeschoolers we might have been interested in volunteering occasionally. That's work experience, learning, and fun all rolled into one! And we're connected with a lot of other homeschoolers - potentially a large pool of volunteers. But I'm not likely to offer to come back now.
There's another wildlife rescue/rehab place in our county. Next time we come across another animal in distress I'll try them first.
