My mom was a foster parent for troubled kids. She did it for 20 years. Over 100 kids ended either being able to return home, or found perm adoption. However, in the end, one kid broke her, and she nearly didn’t come back from it. This kid had a horrible life, abused, physically and sexually for over 10 years by his father and mother both. He got arrested when he tried to touch a 6 year old at his school. When they took him into custody, they put him in a juvi unit with kids 5+ years older then him. He spent 2 years there before he was placed with my mom. He would punch, bite, kick, spit, scratch. Break things, scream, yell, shout, and anything else he could do to try and get a reaction. She lasted just over a year, but when he punched my 3 month old niece, my mom had to physically get between him and my brother who probably would have killed him, no exaggeration. She called and had him picked up by the foster care center she worked for. He screamed at her that like everyone else in his life, she abandoned him. They took him away and she quit the next day. A few years after my mother passed away, I saw on the news that he was killed in a gang related conflict. I’m glad she didn’t have to deal with that knowledge. It took a long time for us to convince her that she wasn’t the one who failed that kid, life just dealt them a shitty hand and they didn’t play the cards they had been dealt right.
