can a gal and boy be only friends( best friends) ??

Recently this question was put forward by my cousin to me, i had to ponder on the issue for a while before answering her. So here was my answer :-
Eventually No, boy and a gal cant just remain best friends, if not both, atleast one will mutually develop a "love" feeling towards the other. But may not realize it immediately. Its just once when you let go of the other person, only then we know the value of the person. Some may not agree with me, specially those who have close friends as either boy/gal. Yes there have being friendships where both usually know each other too well and they are not in love, but they remain "chaddi buddy" ( meaning -best friends). Eventually the society doesnt see them as just friends, they always make up some stories, even if two people are just having a friendly chat on the middle of the road. And then there are movies to be blamed, where they show that boy and gal cant be just friends..they turn into lover one day or the other even though they deny it initially. like for eg, kuch kuch hota hai, Jaane Tu ya jaane na......etc etc.
So the moral of the story by watching all those movies and even your parents watch them, they tend to be extra cautious if their child is spending a lot of time on phone especially with one friend ( of the opposite sex). Then lot of confusion and doubts in everyone mind....so think over it...how many of you can actually say that we (boy and gal) can be best friends ???
Here i would like to bring out one more point, there are some extreme cases, wherein, the guy and gal cant accept their relation as just "friends or lovers", so they claim to the society that they are in a "brother- sister" relationship....they just feel brotherly or sisterly feelings towards the other.....so are they trying to hide their feelings by doing this or is something really cooking???
