Person A has a Facebook account. So does Person B. They’re friends on Facebook.

A is logged on to FB on her browser all the time.

B is over to visit, and logs A off, logging in herself. B leaves without logging off.

A receives a message that someone commented on her status. She clicks the “view this thread” link in the email so she can respond back to it. Does the Facebook website….

A) Tell her that she can’t view the page because it thinks she’s B
B) Log her off of B’s account and prompt her to log back in
C) Let her write comments on the thread AS PERSON B, since both A and B have access to that thread, and she must be B because B is logged in?

If you guessed C, you know why I’m annoyed right now.
