Only will give stickers to (relatively) well behaved children. Or if I hurt you (i.e., gave shots, cleaned ears, etc.). If you are rude, badly behaved and are a typically developing child over four years of age and cannot sit still for 3.8 seconds... YOU. DO. NOT. GET. STICKERS.
And you especially won't get any of my secret stash of lollipops that I keep for bribery.
