TELL 'EM WHY YOU MAD: Sheets in the window

What's good with heads that don't have real curtains or blinds in their window? I have a few pet peeves, and heads that hang sheets or blankets in their windows is one of them. It's not a good look. It's lazy. It's ghetto. It's annoying. Really, how hard is it to run down to Target, Walmart ... hell even KMart and grab some cheap curtains. I understand everyone lives in difference circumstances and money is tight for some, but it's really, really, really not a good look. Get some curtains, please.
