Are there just basically two ways to learn: by experience or by instruction? Assuming it is not good to learn everything by experience (not playing in the street, for example), how much should one learn by instruction? (Please elaborate on this point with examples.) Does the individual child make a difference in this, and how so? For example, what about a 14 year old girl who is fooling around in her bedroom with a boy? How about a little boy planning his own birthday party, inviting whom and getting what he wants?
