There just isn't enough info here to make an educated assessment. First of all, is this girl new? In which case it could make sense if she didn't want to make eye contact, etc., until she knew who was who. Kind of rude... but understandable. On the other hand, if she's been there forever and knows who you are, then her not making eye contact probably means she isn't interested. Also, what are the diff departments? Do you work in shipping and she's finance, or is there at least some kind of relationship between your depts?
Also, how come everyone is always talking about your peepee? It seems totally normal.
