Is it just me or is this getting worse?
You're walking along, someone (or a group of people) come the other way, you both need to move slightly to pass without colliding. Only they don't.
It used to be a thing I noticed men doing - I got so annoyed with having to step into the gutter/press myself against a wall to avoid them, I stopped doing it and let them walk into me. At which point they invariably apologised!
But it seems to happen so much more frequently now, and not with men - usually a couple or a group of women.
Do they honestly not notice you? Not care? Just expect you to disappear out their way?
