What can you do to become a strong and clever boy?
Learn how to exercise!
depends ow strong the 12 year old was or how weak the fully grown man was, chances are, no. i am an 11 year old girl and the boys in the year above mee look quite able to do it though. A strong full-grown man will be too strong for a 12-year-old boy to beat up by fighting with fists but the boy may be able to find another way if he is clever.
