Great Tit

This lovely Great Tit serenaded us when we sat and ate our lunch outside today. He flew off and then his place was immediately taken up by another one.
I met up for coffee with an ex work colleague this morning, and it was nice to have a catch up. She left us about a year ago, and sadly she hates her new job. I didn't ask her if she misses my whistling. I whistle most of the day when I'm working and don't realise I'm doing it until I hear several of the chaps upstairs suddenly join in, or worse still, start singing to my whistled tune. I then stop for a short while, and restart later with a new tune. What was that old saying "A whistling woman and a crowing hen...............?"
