There is no difference because the end result is the same and its the end result that matters
Until her avoidance prevents you guys from finishing work or doing work properly you have nothing to complain about, and if you guys will never have to work together then she has no reason not to avoid you, you don't gain or lose anything if she interacts with you, you are hung up on this for emotional reasons
You are ironically admitting to the mindset I said you had, the end result is the same whether people actively avoid you are just happen to not talk to you, you shouldn't care either way because
YOU ARE THERE TO FOCUS ON YOUR JOB RIGHT?
I don't see why you can't understand your response to this is ridiculous and emotional
If you did not want to talk to her, then her actively avoiding you, or coincidentally not noticing you have the same end result (her not talking to you), so there's no logical reason for you to care, this entire thing is emotional, and it makes no sense because you claim you didn't want to talk to her
This is seriously some petty shit, make up your damn mind what you want
You: "Wasn't even planning on talking to the bitch"
Also You: "Why is she avoiding me and treating me like a leper"
Are you perhaps bi-polar?
