when on nex, facebook, instant messenger or anything of that sort you reply to a msg and they reply back instaniously.(ex, you send it, click to refresh page and their reply is waiting for you. creepy. i know)
it oftens gives the impression that they are just sitting there refreshing the page waiting for you to reply.
