Pet peeve #1: People with no sense of other's personal space. For example,
you place some of you belonging a chair next to you at a nearly empty
table, and then these people ask you to move your belonging so that can
squish up next to you. Pick a seat, any other seat! Or when they come in,
place their stuff in your work space, take off their coat and hat, and look
around for a place to hang it without asking or getting the okay to do so.
Ask or just keep a socially accepted distance until I get to know you
better.
