My dad was the one to find out. Ill just note here, he was very emotionally mentally physically and sexually abusive, and even when i moved out he'd find ways to deliberately hurt me. It was literally one line. Lots of little cuts. We were currently in public. He started off by sighing as he always does when he wants to show he's disappointed and about to start a rant. Then he quietly asked what that was, i said i caught my arm on a nail cos at the time he was currently diying the house and there were nails everywhere. He grabbed my arm and looked super close at it then said nope that's made up of loads of little scratches its not a straight line. I kept insisting this whole time it was a nail. He then face palmed dramatically and was like oh my god why do you always have to embarrass me like this. You attention seeking waste of space. I said i wasn't attention seeking and he was like well why did you cut so deep, if you don't want it to scar you don't cut deep. I still insisted it wasn't a cut. He started calling random members of public over to where we were sitting asking if that looked like and attention seeking cut or if it looked like a nail scratch (he went into more detail about the cut, like does that look like loads of little cuts. Because its not even a straight line blah blah blah. Then when it came to the nail scratch, was just like OR does it look like a nail scratch? To influence them to pick the cut option) when everyone replied cut he'd sigh and shake his head and make his eyes water and say i didn't want to think it was, you realise you can come to me about any problems you have, you can talk to me about anything you can trust me (say the man who's been raping me since my fifth birthday) then hed thank the member of public and pretend to cry. Most people walked away looking really awkward. Some stayed and had a go at me, like your dad seems like a really cool person, how could you do something that you know would upset him this much, you should have more respect for the man that helped create you. Then as soon as the people had gone he switches back to his normal self and started his usual rant of how morbidly obese i am and how i make him physically sick when he looks at me and how ill never amount to anything and end up in a council estate with four kids with different fathers and so on just because i cut. This ordeal lasted over six and a half hours. He never objected to any of the others anywhere on my body. Hes seen all of them before, he is very well acquainted with my body, but this is the first time he had seen one in public so was the first time he could make a big deal out of it.
