Day 9: My favorite tumblrs

What is a tumblr?  I have absolutely no idea.  Is it a mini blog?  A twitter-type thing?  I'm still confused.  Up until a couple weeks ago, I don't think I could have even said I knew it even existed, let a lone had favorites.  However, I do have a favorite (also my least favorite, since it's the only one I've ever read) and it's call To My Wife.  It's sweet.  I like it.  I like imagining that my future husband thinks of these types of quirky things that he's going to want to say to me one day.
