I, too have this problem, more so when it gets light very early and I don't necessarily get up at 4.am unless I'm lambing, but feel guilty about not letting the geese out as they hate being shut in when it's light. Consequently, as soon as I wake properly I rush out, usually managing to swap jim jam bottoms for a pair of jeans, and throw a coat/fleece over my top bit. It's my hair that's the problem. I have very fine dry hair that needs taming in the morning or it really does look like the aforementioned Doddy. Not a good look at all! Fortunately, I have no near neighbours, and very few early morning callers, but you never know!
