I am surprisingly fussy when it comes to wine glasses. Which, considering I am possibly one of the MOST accident-prone people you will ever meet, is not really a good thing.
When packing up our house for our recent move I realised that, thanks to various good nights (and a couple of, well, average ones) we were down to just seven wine glasses. Four of which were actually Champagne flutes. Two of which we never use because they are Swarovski. And were a wedding present. And absolutely cannot be smashed. So the best way to avoid this is to basically use them about once a year. And even that’s flirting with disaster. (Seriously at a house party of a good friend, I once smashed three glasses. In less than two hours. And it wasn’t even dark.)
