I just did something very silly! Embarred!?

My doorbell just rang whilst I was in the bath; ordinarily I would ignore it but I'm waiting for a couple of deliveries for Christmas so I quickly got out and ran downstairs, opened the door. Sure enough it was a delivery and I had to sign for it. I stood behind the door and just stuck my head around the edge of it to talk to the delivery man. Only problem is, my front door is 80% gl! I kind of only realised/remembered after he'd gone. How stupid do I feel? Guess I made his day though!!
