There are a few things that could happen. The first being that they donu2019t realize it. When you have your own kids, they seem so perfect and cool that itu2019s hard to believe not everyone else in the whole world loves them just as much as you do. They may have the exact traits of the kids you bullied, butu2023 well they just wear those traits so well that they are positive things this time, itu2019s totally different.Another thing that could happen is that they bully their child. Thatu2019s right, they start making fun of them and picking on them. Not in a harsh, really trying to hurt them way, but in a u201ctheyu2019re going to be bullied sooner or later for this, so I had better toughen them upu201d kind of way. This kind of parent never really learned that it wasnu2019t the bullied kidu2019s fault for how they were treated.The parent could also turn their childu2019s body guard. They see their kid as the type to be bullied, and decide to protect them from everything. They go to extremes keeping their child away from a society they know will reject them, and may cause the child to not have many friends because daddy/mommy is always in the way of anything that might be construed as a threat.Perhaps the parent would merely realize the error of their ways. They would draw the conclusion that they were wrong for their actions, and use that guilt to power through being an accepting and empowering parent to a kid they are not really sure how to parent. They become very accepting of not only their child, but of other people around them, even though it is outside their comfort zone.There are plenty more scenarios than these, but I believe these are the most likely. If you have other likely scenarios you feel my answer is missing, please comment!
