If you make a very vague request, you're likely to get a vague answer. There's some kind of formal occasion going on in this picture. We have a couple dressed up to the nines, drinks in hand, out for a celebration. Perhaps it's a wedding, or a prom. Either way, it was an important occasion for them, and they didn't want their photo ruined by someone having the audacity to walk down the path in the background.
The suggestion that Fridman should 'do something' with the lady in red was wide open to interpretation. With this Photoshop genius, that's only going to end one way. He did something with her by putting her front and center in the picture. We think the girl who made the request may have wanted to have the intruder removed from the frame, but now it's like she's part of the family.
