Hi. I'm wondering about the sentence Elles ne se sont pas rasees cette semaine./ They didin't shave this week. You would normally associate shaving with men, not women as in your example. Wouldn't it be better to change the subject of the sentence to ILS ne sont pas rases cette semaine, and a week being a long time to go without shaving, the end could be
ce matin, not cette semaine. and you would get a nice sentence
They (men) didn't shave this morning.
