Yes, I know many real boys, many boys who do not always behave in a good way. And from the biblical point of view I know that no man is completely good in God's sight.

Just said that this particular pureness and innocence came to my mind, their good side of character, how they just enjoy life - and I had put sexual thoughts into them. This contrast made me so sad.

Still, in case they do not behave this good way, most of them have a good, pure heart. And even if I cannot see at least a bit of that, I remember they are divine creatures to be loved and not to be abused in thoughts.
