Genuinely very interested in people's opinions on this...
I had a few friends round recently. One was given a curfew by her husband because he didn't feel it was safe for her to be walking or cycling alone late at night. He couldn't pick her up (kids in bed) and she can't really afford cabs (and is too proud to accept someone else paying).
I grew up walking or cycling everywhere at night because my parents didn't own a car, I couldn't afford cabs and it was either get myself home or I didn't see my mates. I know this might mean I'm more relaxed about safety than some women.
I feel to give an adult a curfew and to tell them you're 'not letting them be out alone at night' is quite controlling but my other girlfriends who came round think that women aren't safe, that he's just being caring and she must accept that her night ends earlier than she would perhaps like.
My husband wouldn't tell me I couldn't go out. He might express concern about how I'm getting home I suppose but he wouldn't see forbidding my going out all evening as a proportionate response to what is ultimately a small risk.
But perhaps we're wrong? Very interested to hear people's thoughts and experiences.
