dragging up an old summer memory

when in our twenties one night after drinking too much Cathy and I needed to get home but had no money. she hailed a cab and we both got in. as he started to drive I asked her how we were going to pay. she gave me a look then took off her panties and put her feet up on the seat back. she asked the cabbie, can I pay with this. he adjusted the mirror to get a better look then said you got anything smaller
