Someone just asked me if I had plans for lunch.
It strikes me as odd that 'plan' needs to be pluralized here. Whose lunch is so complicated, so detailed, that they need to create more than one plan? Even so, if your lunch is so complicated, detailed and full of things to do that it requires you to create a list, wouldn't that still just be a plan? Does the 'plans' refer to contingencies in case the original plan gets altered? If so, how many of us make up plans in advance? Don't most of us make one plan for lunch, and if that falls through, then we make another plan?
Don't even get me started on that single item of clothing called 'pants'.
