Maybe they won't wait for me!

I was been held up with mum's at the school pick up, then stopped at the slowest 3 way traffic lights in County Durham, maybe even Great Britain.  On the green light (quite a nice shade actually) I raced round the corner, down the dip, through the wood and screeched to a half - the level crossing ahead was closed for one of those 100 long mineral trains.

Half of me says "great, I can't go to the dentists, it's too late".  Unfortunately MrsDB phoned ahead and they waited for me.
