Upside-down smiley?
According to the description page for this photo, it’s a common street sign in Montreal. That makes me a bit scared of ever visiting that place, since I don’t have the slightest clue what it’s supposed to mean.
Is it an upside-down smiley? Two cherries? Lollipops hanging from a letterbox? Is it warning you that you’ll be hypnotised now?
Weird, weird!
