So I chat message an old friend one night, havent talk to them in a while bit had seen then out the other day, and she doesn't respond. So I close out of the chat, log out, and go on with me day. Next day I log in and theres a blank chat window open from her. Just said (Name) is now offline. Then the following day 2 more windows were up from friends but I hadn't talk to either of them the night before or anything. Are these ppl chatting me when Im actually off and Facebook hasn't refershed? Reason is I wanna say hey back to the first person but don't wanna look like an idiot.
