The day we didn't go swimming

I promised Lillian that I'd take her swimming when we got back from London. However, as soon as we arrived in the car park she fell asleep so I used the opportunity to get some shopping in the supermarket beside the leisure centre instead. Then we ran an errand to the east of Edinburgh and she was very chatty all the way back until the very second we got to the leisure centre car park when she fell asleep again.
