I'm not sure how this happens, but my dogs have figured out how to tell time. Every morning around 5am, they start to bark to wake me up. Not bark, bark, bark, like someone is at the door, but one little bark, then wait 2 minutes and then another little bark. They are telling me that it is time to get up for work. But what they can't figure out is that there are weekends and vacation days where I don't really need to get up at 5am. Then, we all come downstairs and I sit on the couch and watch the news, check my email and eat breakfast and they all go back to sleep. They just want to make sure the day starts right. They could easily come sleep on the couch by themselves, but for whatever reason, it just isn't as comfortable unless they all pile on top of each other and one of them at least has to be touching me to make it all work. I'm not sure who is protecting who here.
