Realistically skiving off is a NO. But it is tempting. (And loads of people do it including many of the naysayers bashing you on here!)
Enjoy your week at work @IKnowItsNotMine Hope it's super lovely and sunny when you are off next! 
When my two kids were little many years ago, I worked three days one week and four days the next ... and for six or seven weeks in a row, whenever I was off, it was always pissing down, and then beautifully sunny on my days at work.
It got me down so much that I actually rang in sick for two full weeks. (Can't remember what I said it was now.) This was the first two weeks in August and me and the kids went off day trips to the zoo, nature parks, the beach, theme parks, woodland, playbarns, parks (swings and slides,) and walks by the river and canal... and a couple of city trips. It was awesome.
There was no Facebook or anything then. Nobody knew. I worked 12 miles away from work and there was no chance of anybody seeing me out and about. One of the best two weeks of my life.
Nearly 100% wall to wall just me and the kids. (DH came on a couple of things but it was mostly me and them two.) Amazing time, and I did really envy SAHMs at that point! Oh it was sunny nearly every day too! (Except two days, when we went bowling one day, and to the cinema the next!)
I was 'salaried' and still got paid in full, but all my work was waiting for me when I got back. A two week backlog. Totally worth it!
