So last week I was slipping further into depression and one of the ways that manifests is that I don't shower. So then I thought to myself, "well, at least the water bill will be lower..."   
Forced myself to shower yesterday (and so feel much better today), and I timed it...I had the water on for 10 minutes. And my siblings, when they shower, have the water on for at least a half hour. So I didn't even save water by not showering, or at least not enough to mention xD  
And I dunno, that struck me as oddly funny, that my attempt to reassure myself there completely struck out.  I guess that means next time I need to find a new excuse for myself!
