Got my hair cut after work yesterday, and the lady was telling about this unusual problem she's having with her swimming pool.
She went to clear off what she thought were leaves stuck to the inside of the pool near the filter housing, and when she touched them, they took off swimming across the pool!
Her "leaves" were actually bats.
That's right, bats.
She had about a dozen of them inside her swimming pool!
I've never heard of bats being able to swim before, but a quick googling tells me that some of them can indeed do it.
So Dina, that's something else for you to worry about when you're lounging around in the pool.
