Friendly Friends....?

I have been told by many people that you are not able to be 'just friends' with a male if you are female unless they're homosexual. I don't understand that statement. I have and have had male friends that I've been just friends with and for some of them it's been a sort of silent agreement. Others, it's been harder to let know that that was all that would happen in that relationship. Granted, I am a very friendly person which is misinterpreted as flirtaciousness most of the time. But all of my friends know this and anyone who meets me realises this very quickly. I have found that it is possible for one to be friends with a male, just not all males will allow that. Some males the agreement seems to have benefits that women don't want unless they're desperate. Good thing a lot of women seem to be desperate most of the time. Unfortunately, women are known as flimsy and easy or bossy and play hard to get. Women seem to be pretty predictable sometimes though I've noticed men can have their predictability as well though I have met one male that has confused me to no end. I'm not saying that all males and all females are able to be friends and be okay with just that. I am only stating the fact that a female can, in fact, be just friends with a male when given the right circumstances... Thank you and see you all on the other side...
