I am a blogger! Go figure

Wow...just like that I am a blogger! Never mind that a year ago husband & I were clueless as to "blog." What's a blog?" we'd ask each other. Finally  I googled the word...imagine that... a web log. Okay I'll bite...what's a web log and why? The world is changing & as I age I am amazed at the rapidity of it all. I know everyone says that time goes faster as you get older but this is ridiculous. How does one keep any secrets?
