Mama mpapa, naine nkakupapa

I was looking for a picture to depict this point and I found this painting by a Zambian artist (Caleb Chisha), which I think may be titled exactly what I was saying.
Basically to 'papa' (is to do exactly what this mother has done for this child) and it says mom carry me like this and I will carry you like this.
Less literally meaning, take care of me and I will take care of you.
I have grown up expecting my mother to give me 100 percent, and she has given me even more than was in her capabilities. I have seen my mother struggle an incredible amount to give me the best she could. But ultimately that just inspired me to work harder because I am committed that one day I will take care of her. I see myself as an investment that will pay off one day.
However I feel like there are stages.
1. first my mom took care of me entirely
2. now I take care of myself (barely)
3. And next I will have enough to give back to her.

Having grown up like this, and still believing this is how the world works. I get confused when I find people still living in their parents homes in their late 20s or even 30s. I have a friend who has a career, and a car, and plans to get married soon but still lives with his parents. The problem I have with this is often, if you sleep in the same room you slept in when you were little, it is very difficult to change the dynamics of your relationship. If the context has remained the same it's difficult for the contents to change.
Additionally something really cool is happening in our family since we have arrived to stage 2, now that my mother is not taking care of me but doesn’t NEED me to take care of her, she can do what she WANTS. She has the joy of being young and able without the stress of having to follow me around and check on me and make sure I am safe.
