Once, I circled a shop five times. It became so bad, the security guard started to shadow me! Why the strange behaviour? I wanted THAT BAG! 

On my first circle of the store, I grabbed it, stroked it, examined it, read the price tag and then decided it really wasn't a necessity and I didn't want to spend that much on a handbag. I then exited the store. 
 
Five minutes later, I returned to once again pick up the offending article, examine it some more, caressed it, sighed and put it back!
 
My third visit saw me standing in the long queue leading to the cashdesk still struggling with my conscience as to whether I really needed to purchase that bag! NOPE, I decided, this is ridiculous. I'm taking myself off home and I am not thinking about that bag any more!
 
This time, I lasted a full half an hour before once again, I was back at the store and discovered to my horror that I'd gained some unwanted baggage - the security guard!!! Okay I thought, make a decision before I'm arrested!  My decision, finally made, I purposefully walked out of the shop and out of the shopping centre. 

Ten minutes later, there I was in the queue, bag in hand, card in the other...I HAD SURRENDERED!
