I've been away from the blogging world for a bit, leaving the blog on auto-pilot, but I'm happy to be back in time to actively participate in T is for Tuesday, a weekly event where we share our beverage of choice and anything else we like. Please join us at Bleubeard and Elizabeth's blog, where a warm welcome waits for you.
