I'm going to say something that could be percieved as very sexist now. Trek is like a woman. When you first meet it, it goes out of its way to impress you. It takes you tp exciting places you have never been, shows you experiences you have never dreamed of, and makes you feel wonderful. After a while, you begin to notice you have been going to the same places, doing the same things over and over again, and the thrill begins to diminish. That is okay, however, because there is still a feeling of loyalty, and an effort is still being made to please you. A bit later, the monotony continues, and you start to ask questions like "why has it stopped trying", and "does it still care about me". You make every effort to make your opinion known, and stick around hoping things will turn around. Then, in an effort to reignite feelings of passion, it does little things like buy you gifts, prance around in slinky outfits occasionally, the occasional sexual fling - taking the least amount of effort to get you to stick around for a bit longer. You begin to think "does it even know me?". Suddenly it's put on some weight, no longer cares what it looks like, or how you feel. It begins to blame you for not feeling the same as you did at the beginning, contending that it hasn't change at all, but that you have. You think "what did I see in it to begin with". Then the harsh separation, leaving it asking "what happened?" Not a perfect analogy, but it works from my perspective.
