How would you react, if a neighbour was giving off strong vibes of... I really don't like you!?

Reason why I'm asking, one of my neighbour's is doing this to me. I live right beside them and the lady there acts arrogant in my presence. I don't care for her either, but I am trying to mind my own business and ignore her. But she is making it more difficult with her glares and acting like she is WAY above me. It is bothersome. Need help with this...
