Well, I have just got rid of one, entirely accidentally when it jumped out of the cupboard at me and shattered into approximately a billion pieces all over the kitchen. I have had the dustpan and brush, hand held and large vacuum cleaners, cloths and a piece of bread out to pick up all the small pieces, but I am sure there must be some left as I just found a piece of another glass which was broken a couple of weeks ago lurking under the dishwasher.
I will now be paranoid about there being bits of glass all over the floor, but we are all (including 2 year old son) dirty hippies mostly barefoot when in the house, and it is unrealistic to expect any of us not to walk around in the kitchen without shoes on.
A couple years ago, a similar incident resulted in me getting a small shard of glass jammed into my foot which refused to be dislodged until it finally came out on a river of pus after about three weeks of throbbing pain every time I stood for more than about 8 seconds.
It has made me wonder why we bother with glasses - sure they feel more substantial and there is something a bit grim about plastic, but the trauma of having to track down every single sliver of broken glass whenever they fall over/into/out of something is so traumatic! Would IBU to smash all the delicate little fuckers in the bin and present everyone with brightly coloured plastic beverage receptacles from now on and for ever more?
