I was strangled and wanted to know what happened. who meant when I turned, I was supposed to have striped his car. however, neither on my nor on his vehicle were any tracks to be seen. (my car was white, his was black, But since I didn’t have time now, and I didn’t like this theader because of nothing, I took my own steps and went off. my colleague said now, but I should let the police and there know, otherwise she could get me up for driving flight. is it true? what should I do?
