I'll be putting up Chapter 5 of 'Lost in the Past' later today. I'll be upping the age limit for this. While there's nothing that happens that requires it, there's a lot of thoughts going on in the head of the 'narrator' that aren't very nice, including some thoughts of committing different acts of violence.
If derogatory terms and someone thinking of doing violent acts would be triggers for you, put it in the perspective that there are are people in the world who think this way, and it's just a character in a story.
