"I'm having trouble"....

Many years ago we were having dinner with a group of friends in New Zealand, some we knew, and some were friends of friends. The conversation developed as the meal progressed and covered many aspects of life in our adopted country.
One of the women was, like us, from the UK, she hailed from Birmingham and had a really good Brummie accent. The topic of little problems came up, and the lady from Birmingham joined in with a comment out of the blue.
" I'm having trouble with me tits", she piped up! 
 I didn't know whether to laugh or keep a straight face.
It turned out that the Blue Tits were pecking the tops off her milk bottles.
We still smile about this, but now we are having the same trouble!
