It's wrong to ignore someone after a one-night stand.
James hooked up with Anna after a party but wasn't very satisfied with the sex.
James doesn't want to see Anna again.
James tells Anna that she's very beautiful, but he just doesn't think they're compatible.
James ignores all of Anna's calls and texts and avoids places he knows she hangs out.
Anna agrees and remains friendly with James whenever they see each other at parties.
Anna tells all her friends that James ghosted her, and he'll probably treat them the same way.
