Anorak

Had the snow been any deeper I could have justified working from home, but it was just slushy enough to deny me that luxury. 
The managers who disapprove of support staff working from home were themselves working from home, so wouldn't have known whether I was at my desk or in my personal loft anyway. 
In their absence I built a drawing so intelligent I can hardly believe it myself.
With no formal training I have created a drawing that calculates the volume of insulation added to a roof, and consequently, the additional weight. - Swoon!
