The facebook friends shown in your chat while offline are the ones that look at your prof?

[Chanel]

It has happened quite often up until now where my brother will suddenly appear on my chat list and then he will call me an hour later and say 'what's with you status'? And the fact that a bunch of guys who never communicate with me at all on fb but are known to like me are always on my facebook chat list when I am offline. It is not based on who you talk with most on fb because a bunch of mine I NEVER talk to or even have tags or anything.
Has anyone else noticed this is true? I have done a lot of tests and every time it is true...
The facebook friends shown in your chat while offline are the ones that look at your profile page the most****
I don't look at their profiles or search them at all.
