on and off

[jasonlulu_2000]

Dear Michelle,
My Dad hates my Mom. He tells me that she is a liar and that I should not trust her. Of course, they are divorced but they have “joint custody” . What a joke! I am a 15-year-old girl, my brother is 9, and we have a life of hell, frankly.
We live one week on and one week off. This was the “brilliant” idea of both of my parents, which was fair to them but ruining my life. I cannot get away from his voice and his putting my mom down. Sometimes I think about running away. What should I do?

What does the underlined part mean?

Thanks!

Jason

It means you live one week in her house and the next week in his.

***NOT A TEACHER***
It is worth having a look at this worthwhile post:

​

I would say that when preceded by "my", then no capitalisation is required:

Every day, my mum and dad kiss me on the cheek.

However, if you remove "my", then they are being used as titles:

Every day, Mum and Dad kiss me on the cheek.

In BrE, we don't use "Mommy". We use "Mum and Dad", "Mom and Dad" (Midlands/Northern dialects) or "Mummy and Daddy".
