It is not up to you to try to force the kids to do anything but be polite, nondestructive, and not put themselves, others, or property in danger. You offered an activity which was rejected in a normal pattern for this child, so not being his parent you really shouldn't pass judgement on his being spoiled, lazy, precious, etc. The child may have underlying problems you (and even his parents) are not aware of, and it is not your place to try to force them to a head.
The polite, reasonable, and safe thing to do is just let the kid play quietly if that is what he needs to do, be it reading, drawing, playing handheld games, or watching TV in just the short time he was with you. [/i][/i]
Recent events have taught me this about children that I am not completely responsible for.
