Oh so many. However, this one comes to mind. I sleep naked and was in bed with my little girl (aged about 2–3). Someone came to the front door so I got out of bed, grabbed some clothes and walked to the front door and started to get dressed, at which point my daughter, helpful little soul, opened the front door wide and I stood there half naked looking in horror at the stranger on the door step.
On a similar vein, my ex husband was in the shower. A lady came to the door selling kids books so I let her in. She was a tall and beautiful Swedish student making some money on a working holiday. So, we were talking in the kitchen and looking at books, when my naked husband opens the bathroom door and comes rushing out to naked because there wasn’t a towel in the bathroom. He had no idea anyone else was in the house. So they stood there staring at each other .. mouths open in shock and I fell about laughing. She was cool about it and I did recover enough to throw him a tea towel.
