on what should i put my food?

I have this “thing” concerning dishes.

I can’t quite remember each dinnerware set we’ve used in twenty-seven years of marriage. The precise reason for this “affliction” is unknown, but if I see something different that I like, I think I want them, for a while anyhow. I’m not sure if I get tired of what we’re currently using, or if I just like playing musical dinnerware. I enjoy looking at new styles and have seen several whimsical sets lately. I wonder if it's time for a change?
