Underwear embarrassment

Chris got up early this morning as he is working in London this week and will be spending quality time with his family in Broadstairs until Sunday. So there was much hurried packing and huffing and puffing before I had to take him to the station, so whist still half asleep I dressed, fed and watered the field then drove to the feed wholesalers to buy corn and chick crumbs.
On the way back I stopped at the spar garage to buy some cheap cat food (to build Blanche up) and as I was standing in line I could feel a single unnoticed sock slipping slowly down the inside of my leg!
I don't know if this happens to other blog readers, but sometimes after dressing in a hurry, I occasionally find a previously worn sock hidden away in a pant leg, generally you notice it straight away and can have a delve and drag the smelly article out.....this morning I must have been so sleepy that I did not notice anything, so I was mildly surprised when I felt a sock "plop" gently down my leg and onto the floor of the spar shop!
How wrong I was .....for it wasn't a sock that I saw lying on the floor.....it was in fact a screwed up pair of grungy work underpants!

Before I could pick them up I heard a woman's voice behind me say "I think you've dropped something".........and for a few seconds I wanted the earth to swallow me up whole!
At least the woman behind me was the only person in line. and without gazing at her directly and looking like a beetroot, I pick up my underpants explaining lamely " I have just got up!"
She snorted as did the woman behind the till and I had to stand there, pants rolled up in hand , for an age until I could make a run for it....
message to self.....throw old pants in the laundry basket as soon as you remove them!
