This reminds me that some of the best parts of ourselves are those parts which are most adaptable, but more importantly--the more flexible.
Any part of us that is severely rigid--it usually seems to be the part of myself I like the least. It's a judgmental part of myself if it is severely rigid. It's also a part of myself that is not open to new ideas and viewpoints.
I was reminded of rigidity yesterday seeing my minister mother. She's so severely rigid, and I was so severely stressed in her company.
I like the child in each of us that embraces new things, and loves discovery, and the beauty in a child's eyes when they light up with that discovery.
