My sister who lives in the US came for a visit over Christmas and stayed with Mum - pwd. One of mums obsessions is her handbag and purse, she spends hours going through it looking for her purse and counting her money. One afternoon after leaving her bag in the lounge while going to the bathroom, my sister found that her purse was empty when she got back and mum had some dollars mixed in with her notes in her purse! Mum of course denied touching my sisters purse.
Just then a taxi arrived to take them to a local restaurant to meet the rest of us for a meal. When in the taxi, my sister began scratching around in her bag and pockets for some cash to pay the driver and asked mum if she could get her purse out. Mum then said "I suppose you think I stole these coins from you as well?" And turned to the driver to complain that my sister constantly takes money from her and leaves her with no cash! My sister was humiliated and embarrassed!
That taught her not to leave her handbag lying around!
