Well Anne,
We, somehow, have spent all our available funds for the catering for your party. Sorry, but I inadvertently spent it in the gin bar yesterday.
So we decided to come and pick you up ourselves, but we have had a bit of a mishap. I can't figure out why the accident happened.
However, every cloud has a silver lining. We were rescued by some hunky, chunky paramedics and they have agreed to come to the party with some of their colleagues. Perhaps we could ask them to pick you up in their ambulance. After all, I think we may need them once the party gets into full swing. Along with the firefighters, I'm sure we are in for a night of it.
