Watching the wobble

I overslept this morning. So I was late for work. So late I used the car & damn the environment. Anyway, I'm in the lift and a young girl gets in. She's very pretty, quite short & has her blouse tastefully unbuttoned at the top. And I’m tall. And I can see straight down her top. Have to say that they were a good pair for a small girl. Suddenly I realise I'm staring. I glance up to see if the girl has noticed. She has. I'm suitably embarrassed. The lift stops & just before she gets out she leans in close & whispers 'your fly is undone'. Damn.
