There are probably a thousand 17 year old girls in the US that sunbath topless in the back yard and have 14-15 year old brothers. By the time he's 14 he's seen it all a hundred times. It's no big deal.
When I was 17 I sunbathed topless on a beaches in Europe and there were teenage guys running around me all over the place. They couldn't have cared less about me. Just another sunbather, they see those everyday.
If they are in the privacy of their own back yard, of course it's legal. She and/or he can also be completely nude if they so desire. As long as there is no sex involved, not a problem.
Nothing wrong with being nude and losing the tan lines.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
