When my eldest was a year old, we were in Chicago visiting my sister - and she served spaghetti. He was watching my sister and mimicking her actions that evening, so she pretended to pat her spaghetti, then rubbed her head. Naturally, my son slapped the spaghetti, then rubbed his head..... This proceeded for several minutes until I figured out what was going on (was distracted by my nieces at the table)
By the way, I think they were fairy eggs. I have a fairy garden on my patio, and I think they got lost coming here ~Jan
