A manual, a boundary and a tattoo

On one of the coaching calls this month Brooke referenced her son wanting a tattoo. She told him he couldn’t get one and if he did she was withholding money from him.

Can you clarify whether this is a manual issue or a boundary issue? It seems like manipulation when we withhold money from someone if they do something we don’t want them to do but I guess it also depends on the age of the child.

Can you clarify this for me?
