Knirps for Moisture

This is pretty freakish, on a variety of levels:

Cupid's Double Umbrella

However much you're 'into' someone, there's nothing more irritating than having to share your umbrella. Yes it seems intimate and cosy, but let's be honest, it just doesn't work. Either they're so short that your head's in the spokes and they still get wet, or they're so tall that you're way below the height where you get any protection at all - and of course you both end up with one very wet shoulder each. Then again if you both have an umbrella you simply can't walk abreast, if you try, you inevitably end up ducking and diving around a tree, making way for glowering passers by, clinking spokes with the other umbrellas and putting your conversation on hold until you reach dry land. Oh the social pitfalls of umbrella etiquette!

Question, though: How does it close?
