Why are Mondays so tiring?

[fancytalk]

Or rather why, after two days of not having to be somewhere, is Monday the hardest day to get up? I'm so tired and the only thing I want to do is go back to sleep. It would also probably help if I went to bed at a decent hour. I'm driving the dog crazy with my late nights, the cat on the other hand loves it. I'm going to attempt to right my schedule. Then maybe I won't look at the juniper as something that might kill me if I get too close.
