More than I can chew

I mean of course, that I've bitten off more than I can chew. I've just attempted to clean the "Yorkie bars aren't for girls" truck. I knew it was big - but now that my back has gone and I'm knackered and the car doesn't really look all that clean because I've missed so many bits and I'm fed up and tired...I have realised that cleaning said vehicle is a job for boys - ie boys at a valeting centre.

I will not be attempting it again.
