Falling glasses. When you need reading glasses but can manage without them. You rest them on your knees- then they fall off! I was taking a photo of my cat but fumbled with the phone and snapped (not literally) my glasses instead!

What a view

Falling through

The air

Onto my shoe!

You were meant to be

My cat

But as you can see

From where they sat

On my knee

Glasses – not a cat

Fell flat

Splat!
