At what age would you have that talk with your daughter so she’s not surprised by street harassment and treatment by men around her body? And any comments or insights on how would be good too.

UPDATE
Thanks everyone for your comments and insights. I had a little chat with her before she went out today. I used some of your words like “if someone makes you feel unsafe then they are not safe to be around”. I advised her to ignore and move on and if necessary seek the safety of the nearest woman, they are just likely to understand if you say you don’t feel safe even if you don’t know why.

Really appreciate you all here, thanks for helping.
