I have not spoken to my sister for around 15 years, because she is selfish and caused a lot of problems for herself and others.
She had a child at quite a young age (19) and she didn't know who the Father was, she got 5 DNA tests done for Fathers all came back negative.
When her son was 2 years old, she started a relationship with a guy who social services were following, and they advised my sister that she was not able to continue a relationship with him because she had a young child, he was a convicted child molester who had abused a young child in his own family. My sister decided to continue a relationship with this person, after telling scoial services she would end it, they found out and gave her a few more chances to end it, she didn't. Her son was put into mine and my wife's care as we didn't want him going into the foster system, we ended up Fostering him for 10+ years.
My sister caused so many problems for us when we fostered her son, because she was jealous that we had her son. It got that bad that my wife worked at a school as a teaching assistant and my sister sent pornograph images "presumably" downloaded from the internal of some weird lesbian images but with no faces and wrote a letter to the school claiming it was my wife in the images, of course it wasn't. The letter was not signed but when the police got involved they obtained some of her handwiriting and there was some similiarities in the writing style but she tried to mask her writing and it was enough that the CPS and police said they could not take further action even though they believed it was her doing. Other minor things happened over the years also, but this was the worst of them all.
My sister also stole money from my mother towards the end of my mothers life (my mother had MS and was in & out hospital a lot for the last 2 years of her life) My isster stole money from her, and she even open credit accounts with various calatogues, credit cards etc all in my mothers name without anybody knowing until my mother died. That was a mess to sort, and actually my Dad had to pay most of these debts as it was nigh on impossible to prove they were fraudulent credit accounts.
My sister I believe is into drugs and has never worked in her life and just sponges from the tax payer.
I have not seen or spoken to her in over 15 years now and this is how I wish for it to stay.
