I'm going to see a band in a pub, about 30 mins walk from home.
I'm going with a group of male friends, all completely platonic. I know they will be uneasy about "letting" me walk home. There will probably be one or two going in my direction for a while, but some poor soul will feel obliged to walk me home, thereby extending his journey or suggest sharing a cab, thereby incurring a cost that neither of us needs.
I hate getting in a cab on my own and am happy to walk. I feel far safer and more comfortable walking.
How do I make these men see I'm OK walking and if something awful did happen it's my choice, not their problem.
