What made adoptive parents return their new child?

I had a neighbour named Melissa.

She was about my age, like eight, and her brother was slightly older, Giovanni.

I remember when they moved in because her baby brother was named Kermit, and I thought

that was extremely bizarre.

She was eccentric to say the least.

My mum let her come over pretty much whenever she wanted during the summer, because she always seemed to be ignored by her parents. Giovanni used to come over too, but I remember he'd leave a lot to go run errands with his parents or for dinner. Whenever I asked her if she had to go, she said she couldn't eat what they could or go with them anywhere. They basically shushed her out of the house. It was concerning, so I told my parents.

My mum tried making friends with her mum several times, but the woman was just cold. Anyway,

turns out Melissa was adopted. I'm not sure how my mom found out, but I remember coming home

from school one day, and Melissa just wasn't there. She normally waited outside of my house.

A week or more went by, still didn't come over.

Our neighbourhood was very gossipy,

but someone found out they gave her back because she was chatty,

and they originally just wanted all boys.

Her family moved out shortly after this.

I have an ex-girlfriend, let's call her Rosie.

Around 2008, when we were both 14, both her and

her infant sister were in foster care. Shortly into our relationship, a couple with a six-year-old

boy decided they wanted another child, but didn't want to undergo childbirth again.

So what they did was adopt her sister and give Rosie a short time to live with them as a

foster child to see if she had fit into the family.

Understandable, they kept her for around two weeks and then said no because their biological son wanted to be the oldest.
