long way home

You where on your way home after a long day of school when you decided to take the long turn since it was the last nice day of the year. your friend would normally have walked with you but she claimed she was to tired and just wanted to get home. you promised to check up on her and see how she was doing since she hated walking home alone no matter what time of day. as you were walking you started to get this feeling in your stomach that you shouldn't have let her walk home without you and you should have gone with her. While your walking she suddenly stops messaging and you just assumed she had made it home. but when you get a message from her mother after you had already been home for over an hour asking if she was with you, you got that feeling again and started to panic. What happened to Grace, and how come she didn't make it home
