Tested with CPython 3.7.3
```
from pathlib import Path
p = Path('.')
assert p == p.parent # should fail but it does not
```
I expect Path('.').parent to be Path('..')
I searched issues and did not find any similar issue but maybe I didn't search well enough because I would be surprised that I'd be the first one to be bugged by this issue.
I didn't test newer version of Python as I couldn't find a package or wasn't comfortable enough to build it myself.

This is by design. The "parent" attribute is a *lexical operation*. If you want to walk the actual filesystem, first call resolve(). It's even documented: https://docs.python.org/3/library/pathlib.html#pathlib.PurePath.parent |

T-T Sorry. It didn't feel intuitive but I should have read the doc... |

Would it be worth to set 'parent' to None in this instance? Might break code but would also be potentially less surprising. |
