I knew it was only a question of time before my sister called and asked if she could come to my place and talk. I knew because a few days before our mother told me she found out her boyfriend was cheating on her with one of her friends and she was devastated, and I know she only knows how to deal with this situation by also doing the same her boyfriend did with her, a kind of eye for an eye. And I'm her first option because she can feel she got her revenge without feeling guilty after. I know it sounds a bit weird but her head works this way.
