I am continually amused - I moved beyond "perplexed" a while ago - by the fact that pretty much everyone I'm intimately involved with insists that I am made of fire. Note: people I'm not involved with have also been known to tell me this! But I can't remember the last time a lover didn't. These are people who in some cases don't know each other, and wouldn't have picked that idea up from each other. Still. Always. Made of fire. "Liquid fire" is the newest variation.
Related: I am told by most people that I am much taller than I actually am. I have learned to not be perplexed by this either.
