You're right, but your sister was very lucky to find a man to propose to her.

I also have a sister in her late 30s, but she's a single mother and an eternal liability to my parents. We tried giving her advice but her whore genes were too strong. She will be alone for life.

I hope it doesn't happen to your sister too because "she thought she could do better" or "he's too nice and stable".
