I don't understand what you mean by "trapped."
The fact that the writer expects someone else to pay for, and care for, his/her ailing mother tells you what that means...Having worked in the healthdare field, I am familiar with these types of children. It’s part of the communist plan to make everyone part of the welfare states.
