Does The Friendship Between Boys Ans Girls Should Be Prohibited?

First off, please re-phrase your question to make sense.  Maybe learn english.....  To answer what I "think" your question is, in the United States, there is nothing that prohibits laws between boys and girls.  THAT would defeat the purpose of relationships in general unless of course you feel there should be a nation of nothing but same sex relationships which wouldn't make much sense because our race of humanity would die off very quickly!  Also please keep in mind that a lot of people would be in prisons everywhere because nature makes boys and girls go together.   Same sex relationships are fine and very often better than the usual types of heterosexual relationships!Sorry if I offended at the beginning of my post.  But I hope this information helps you out!  Good luck in love & life!
