I have been so late posting reading all of these hilarious tales. OP has sorted it for today, no need for my madcap suggestions at all...
I have my own embarrassing confession, I've posted it before so apologies
There was a man I was besotted with, I found out that he shopped in Co-op every week so off I trotted in very high heels and dolled up to the nines.
I saw him in one of the aisles reading a packet that he was holding. I sidled over to him, leaned across right in front of him and did what I fondly thought was a seductive 'bunny girl dip'. Of course it was nothing of the sort, I started to tip, couldn't 'right' myself, grabbed the edge of the shelf (which came off in my hands)... and I slid to the floor.
Instead of getting up again when he proferred his hand, I said "No, it's fine, I'm just tired", put my head down in my arms and pretended to be asleep. 
==================================================
I can't bear to think of it, it's all come back to me now. 

If I'd only just taken his hand, laughed at myself and got up from the floor, we could have been a perfect couple by now... instead of which I was the maddest woman alive and only now feature, if I ever do, in his worst nightmares...
