rolling down a grassy hill

Remember doing this as a kid? I loved doing this. But it always kinda hurt, and was a bit disappointing. Yet I did it every time I saw a big grassy hill (and was allowed to). Charis is the same. It always tempts her, and she is generally a bit disappointed. But I love watching her do it. And then there's Pax who wouldn't even walk on grass without shoes for a long time. I think he tried rolling once, and has never been tempted since. My guess is that Jonas will be a roller.
