I have three coffee cups, on rotation, so there's always a clean one when you need it. I care about them because they meant something for me at the time I got them. I'd be sad to break any of them, but then I'd have other two waiting to be used. I do not approve of seasonal mugs. What's the point of using a Santa mug in April? That's a waste of money.
Someone recently gave me a set of three very cute cups, only they're too small for coffee or tea. What am I to do with them? They're just sitting on the kitchen counter, being cute, but that's all. Cute crap sold for the holiday season...
Also, for the record, when I need coffee, I'll drink it out of anything...
