What parenting responsibilities? She's 27 now. She doesn't need any lessons taught to her, she just wants to apologize and have him back in her life. And it won't be just her father's call. She terrorized the entire family and her step-mom is going to have a major say in how much contact she's going to get with the family. But, again, she's an adult, knows exactly how all this went down, and is willing to take 100% of the blame...yet for some strange reason you're arguing with her assessment. No doubt she'll have a lot better chance of mending fences if she owns up to what she did, rather than offering a half-hearted apology based on the idea that it was somehow daddy's fault she was building booby-traps in the house.
