Did Not Have The Slightest Idea
At the time, she did not have the slightest clue that she took a photo of something else. It was a selfie, but she failed to notice that she was not on her own. Her friends had been the ones to point out the truth about her photo. They were so shocked that they lost it. They could see an intruder in the photo!
It Was Not An Ideal Morning
Olivia only took the photo to share the state that she was in. It was not hard to see that she had a rough morning. You could see it on her face! Her friends must have felt sympathetic, but not surprised. After all, this was the normal course of things after a night out. The pain was evident in her eyes.
