We have a large collection of left-hand washing up gloves as the right one always breaks first, presumably because we're both right-handed. I don't like to bin the left hand glove as it's still usable and seems a waste, so I keep them.
Sometimes I use a left-hand glove on my right hand to use them up. MIL says she turns a left-hand one inside out to use on her right hand. I've often thought that it would be helpful if a pack of gloves came with a spare right-hand gloves, or if you could buy single gloves. Are we the only people who have this problem?
YABU - just bin it like a normal person
YANBU - shops should sell spares!
