Facebook chat confusion?please help 10 points for best answer!?

[578]

Okay so you know how the people you chat to most on Facebook are listed at the top of the chat bar?Well that happens to my chat,mostly. I'm friends with this guy that I never really talk to,the last time we talked it was the end of January,and before that one time we hadn't talked since last summer. I'm just wondering why he's always at the top of my list of people on Facebook chat? Does this mean he looks at my profile from time to time and that's what keeps his name up there?The only time it goes down is when I'm in the middle of talking to one of my best friends,then his name will move down one,like only the people I always talk to are at the top,and then some people who I talk every week or so...and then him at the top?? I just want to know is there any reason for this?:/
please help anyone who has any idea as to why this is happening,I don't particularly like being reminded of this guy,I haven't seen him in person in 10 months and he's well,the only person who made me actually have human emotions,so yeah,I'd like to know why Facebook likes reminding me that I'm fragile every time I log on :L

I don't know why, but if you don't want to see his pic you can do that by turning off chat with him. Just click the gear icon on top right of the Chat, then click Advance Setting, choose the option that fit to your preference & put his name as the one you turn chat off. Anytime, you can change this setting.
