Party Plans

There was a second silence before Mark's carefree tone came on. "I don't see how that's any of my business."

Eric let out a sigh. "I know. I just wanted to know what you think, you don't need to care about her ways."

Eric just didn't know what was with his brother and ruining conversations. They were like five and six. He just couldn't get it.

"Well, she is free to spend her money however it pleases her. I don't give a damn about her relationships with other people as long as she doesn't drag us down with her."

Mark's stand was very simple and easy to understand. He did not mince words and he did not try to pretend. 

He was not hiding the fact that he did not care about their younger sister and her affairs. Maybe the only reason that would make him step into their sister's affairs would be when it became life-threatening.
