You're responsible for your own safety and I always ensure I can get home, with a back up plan if necessary.
Sadly, as a woman, if anything were to go wrong, or you were attacked, you would ultimately be blamed in one way or another.
Men will never understand why women sometimes worry about their safety, they won't even accept that it's because of them we worry about our safety.
When Nicola Everard was murdered, I remember seeing one comment from a man, on Instagram on the Mirror website and he simply said '"she had trainers on she should have run faster, it was her fault for taking the risk to walk home, it's on her" I screenshot it and sent it to his employer which he had kindly put on his profile. He was a Teacher and held that opinion.
I fully expect the NAMALT to be on this thread soon, blaming you or anyone who worries for their safety but I get what you're saying.
I always check my female friends have made it home safe and we always check in with each other.
