Vovo wants Zethu to be her surrogate, but she also wants something in return.
Vovo now wants to have a baby but she is not sure if she will be able to carry her baby on her own, that is why she has a hard request for her close friend Zethu. Vovo believes that a baby needs enough room in her body to able to kick and feel comfortable.
She asked Zethu if she will be able to carry a baby for her but they will use her eggs. She wants Zethu to be her surrogate, these kind of things do not usually come for free. Zethu asks if she will get something out of it, and I think it is money and nothing else.
Vovo and Zethu are friends and it will be good for Vovo to compensate her or even if she does not. Vovo did not ask to be born this way, and it will be a great gesture for Zethu to do it for free.
