Hands up hands up ! I am one of the ones who just like company somtimes, if I am feeling unwell I like to 'read' the room I say hi to everyone and point out I am unwell and will be quiet and say hi to anyone else who joins the room but I dont explain myself to any one who has joined I only say it the once its nice to have company when you are feeling scared or lonely and reading the room is a nice sense of not being alone.
