The morning the pan talked to me

How weird can life be? I went into the kitchen this morning, still sleepy, and stopped frozen in front of my stove. There was my pan, standing there since a week or more, and in the middle of the oliveoil a big heart!
Now what is my pan trying to tell me by offering a heart?
Love is in the air today? Time to ponder about Valentine's day? Or - more profane - time to clean the kitchen?
I thought a bit (not easy, since still half asleep), and opted for the cleaning. Now I know what to do today after Winterfeldtplatz market...
