The core issue let me reveal that no usually adult occupation would be feasible, as individuals would notice (sooner or later) that the kid just isn’t aging during the fast price kids that age usually would. Additionally, youth have a problem establishing on their own as professionals (so no body would think them to become a doctor that is qualified attorney, or engineer). Any long-lasting contact with the exact same individuals is dangerous and cause rumors which could expose the key. Moreover, being fully a nomad would not be simple at that age because governments will be expected to make an effort to adopt them into a property or orphanage, which again leads to the people that are same them across long expanses of time.
This renders just a few options:
Being truly a thief could be an option that is surprisingly good. No body would think a young child that age could break a home in a particular means, or have knowledge of selecting hair, or any.
