We have no idea why this person's friend was pulling that terrified face on the original picture. It might just be a case of unfortunate timing, but there's no denying that she looks like she's running for her life. To spare her blushes, Fridman has been asked to put something in the background of the shot that would make sense for her to run away from. He's done that, but probably not with the kind of terrifying creatures the sender had in mind.
The Teletubbies have been adored by two generations of children, and they're not frightening at all when they're in their own colorful land on their TV show. If you take them out of that land and place them on an everyday street, they're suddenly not so cute. Nothing has changed about their appearance, but instead of being cuddly, friendly giants, they're horrifying alien creatures who probably want to eat you. We'd run away from that, too!
