This post was inspired by a recent experience. My friend, who I love dearly, has a sister who is the most TERRIBLE person on the planet. She hurts and manipulates my friend, smokes marijuana in front of her kid although he is so allergic to it that it causes seizures (don't ask how this happens- it's RARE to be allergic to marijuana) and does the MOST messed up things. I hate maybe two or three people in this world, and she's definitely one of them. So my friend spent the night at my house and was talking about her sister. She told me her sister liked being choked and one day came home with popped blood vessels and bruises all over her throat. From reading Sebastian's post about breath play in the FAQ, I knew the dangers of such things... And I thought to tell her, but then stopped. And I said "Oh, I hope she has fun with that." Now although they don't talk anymore, so it's not like my friend would ever be able to pass this information along to her sister, I later thought about this and how I probably would have not said anything even if they were still talking or even if I saw her sister in person... HOW MESSED UP IS THAT!?!??!?!? I tell anyone and everyone all the safety information I know about anything all the time. I once had a nickname of "the safety police" in one of my classes. Everything from children to safe sex to emotional safety to wearing your freaking seat belt- I tell people this stuff all the time whether they are my friends or not... I don't tell them what to do- it's just so they know, since that's what I'd like someone else to do for me. If I'm choosing to take a risk, I'd like to at least know I'm taking one! So it freaks me out I could be so uncaring about this person. Has anyone else ever done something like this? Do you think it is immoral? Is someone obligated to tell someone when they are risking their life if they possess knowledge about said hazards?
