It is very much out of the ordinary for a woman to walk home from Sarnia to Courtright at anytime, let alone after 2 AM. The walk would easily be 2-3 hours. If someone were to do this they would probably hitchhike. It's common to see a lot of hitchhikers on this route.
But I highly doubt that this was something she's done before. She doesn't appear to be a hitchhiker type considering that she's in her late twenties, a good job (teacher) and apparently has lots of friends and a stable family. She would probably never need to hitch hike. So I don't think it would be right to suggest that her friends would think it's okay that she walked or hitchhiked home.
With that said, I have no idea how many friends she was with and who or why any of them didn't make sure she got home safe. I'm sure they are all having a hard time dealing with that right now.
Oh, I agree. As soon as I heard that people were saying she was going to walk home from downtown Sarnia to Courtright, it seemed odd to me. That's an impossible walk in the winter, in heels, at night. I don't know anyone who would even consider it.
I also feel terribly bad for her friends who were there that night - what an awful burden to carry with you. This is not their fault, but I am sure they will need time and maybe help to work through the feelings this incident will bring up in them. It is odd that no one made sure she got home safe, but saying that again, we actually don't know what happened.
