Let’s play “how do you explain this to Grandma?”

A link to this blog turned up in my inbox this morning, with an attached note addressed to me and my little sister: >>This is my first cousin Arnold’s daughter. I never saw her. I do not know what this means. Can either of you explain it. You can tell me when you get here if you have no time now. Love, Grandma<<

Okay, let’s play the game. You’ve just woken up. You’ve clicked through and read the blog, and watched the video. You pretty much get what they’re up to (e.g. miscellaneous corporate nerd stuff). So……..keeping in mind that your goal here is not to snark your heart or out, sow confusion, or express derision, but rather to communicate just enough meaning to satisfy the person who asked the question……..H0W DO YOU EXPLAIN THIS TO GRANDMA?
