A wine glass got knocked over on shabbos and broke on the kitchen floor. Normally, I am exceedingly good at getting all the shards of glass up - leaving no trace behind. Apparently not this time - I have a tiny shard of glass in each of my feet. It hurts a fair bit, though nothing intolerable. Mostly it's just aggravating to know that every time I step down on that part of my foot (e.g. every time I take a step), a sharp pain will result.
