Escort is a very specific field of specialty,  when it comes to a friendship. It looks more like mutually beneficial cooperation between girls, than a friendly affection. The point is: we compete for resources. And, when the most precious elements (guys, their money and attention, possibilities, that such connections can provide with) is at stake, we rip each other apart. In a metaphorical sense of course. Very often girls sacrifice a long-standing friendship to win a guy. In most cases such victory is ephemeral and short-term with a foul aftertaste, because guys are always back to their dearest, and girls have to face the reality, that stands with a feeling of being left and with a crack in a friendship. Yet there is also an exception: smart girls, who set priorities in favor of their friendship, because only a woman can understand a woman.
