Browsing Bliss Awaits You

It appears you're using Internet Explorer or an early version of Edge, which is a bit like watching a black-and-white TV with "rabbit ears." You're missing symmetry, joy and actual knowledge — not only here on my website but across the internet. I suggest you upgrade to Chrome or Firefox. You’ll discover a lot more nature, maybe even actual rabbit ears.
