The girl sitting beside the guy is his gf?
Probability is high, because they wear the same type of **** specs and they look like a perfect item.

Ways to avoid being take as a pervert in this type of situation!
- Don't avoid the camera just show your hands in peace or V-shape and smile!
- Think it as a friends taking pictures
If the picture is shown, then other people saw it will think that
- Is that your friend? How come he smile and don't feel guilty and he feel
comfortable with you taking his picture!
- If the guy in the picture was question by his friend, then he can answer, I
also not sure how it get into there with reason like people hack into your pc
that day or your friend take revenge on you because of some
misunderstanding.
So there are ways to avoid! Because i used to be in this type of situation!

Not that stupid to get caught!
