Here's a great post, with an excuse for, well, everything. Couldn't say it better myself, so I'm not going to try. But if you're someone I've offended, well... as the man says, "It's not that I'm inconsiderate. I'm just lazy, and overwhelmed. I'm trying to read a book. I had to get out some. My dog needed to go to the vet. It's in the mail. I swear."
