Deleting pals from online friends list is emerging as the latest offence in the world of social networking.
Most people are just getting used to the idea of social networks in general. But the complicated and evolving rules about what constitutes friendship online is adding even more stress.
A 21-year-old student at Pace University in Manhattan had to face someone she defriended on Facebook in a chance encounter on an elevator, and re-added the person to rid herself of the guilt.
JoAna Swan recently purged her profile on the social-networking site Facebook of friends she hadn't spoken to for a while.
A week later, crammed next to Swan in an elevator on the way to class, the woman, an acquaintance from freshman year, called her out for "unfriending" her and asked what she had done to deserve it.
Swan considered saying it was an accident, but then opted to be honest.
"It's nothing personal. I just delete people I no longer talk to," Fox News quoted Swan, as saying.
A week later, she ran into the woman again, and decided to refriend her because, "she seemed very offended by the whole thing."
She declined to name the woman, noting that it would "make things more awkward and turn into another whole drama-fest."
