I was walking to work down Canley Ford, wearing my big headphones, when I decided to take them off to hear the birdsong. The cool air was quite pleasant so I said (probably silently) to myself 'fresh air on my ears'. It struck me as such a silly phrase that I said it aloud in a silly voice 'Ah! fresh AIR on my EARS!' and then I saw a guy walking his dog looking at me as if I was nuts. Sigh.
At lunchtime I was in a cafe when I overheard a guy talking to his workmates.
'Sex hasn't been easy lately, what with the little one in the bedroom. And the new baby doesn't help either!'
I thought it was an excellent self-deprecating joke, with a great lead-up.
