It's a HUGE deal tinyrabbit. You are NOT making a fuss over nothing.

And you're absolutely correct when you say that the thought about pajama bottoms is faulty thinking. It wouldn't have mattered what you wore, it would have happened anyway because your father is abusive.

Trigger Warning for this part:
I think, when someone gets abused, you get defeated. You would feel like no matter WHAT you did, you wouldn't be able to stop it. That's what the abuser wants you to think, and it's what they convince you TO think. That it's your fault. It's wrong - it's not your fault! But you really couldn't have stopped it. Perhaps with the pajamas tinyrabbit... perhaps it crossed your mind back then. That maybe wearing pajama bottoms would stop it. But then you would have recognized that he would have continued to abuse you anyway - and maybe if you were wearing pajama bottoms, it would have made him either rip them off or make you undress yourself in front of him - which could have maybe made it feel even more humiliating and traumatic? I'm just taking a guess here... but I would guess that you were actually trying to help minimize your level of trauma, and you were also avoiding making him angry by trying to defy him in that way - because goodness knows, anyone would be terrified of what might happen if they actively resisted.

You did not invite it tinyrabbit. You did not invite it.
