It turns out that not only teachers at school are strict, but also strangers who got on your selfie! At least the woman in the sunglasses looks very serious. Moreover, it seems that she is unfriendly. Maybe she gets annoyed when she is in other people's photos or just had a bad day. What would you do if you noticed that you were in a selfie with a stranger? Would you ignore it or go to swear? Or maybe you would look the same as the woman in the photo? This looks pretty intimidating.
