Why do some women give me dirty looks for no reason?

Like I'd be sitting waiting for a bus and I'd just look in their direction for like 2 seconds and almost instantly they'd fold there arms and give me a dirty look and keep eying me back and forth.

Some women will go like pfff when the walk past me only one has ever said eww

How can I make this stop I'm not evening looking or staring at these women it's just if I look in their general direction for no longer than 2 seconds

So it's not enough to be ugly you have to be insulted by strangers as well -_-
