I started returning carts after seeing posts about this on that other site. It wasn't that I didn't care about being a good human in society, I just didn't know it mattered and hadn't thought about it. My mom taught me growing up to ensure that it wouldn't roll away and hit anyone's car and that's as far as that topic ever went.

So I find it hard to blame people for not doing things like this, it takes time for society to grow and change. I think in many ways we are (and this is what has the right wing in a panic).
