When you order a drink, take a first sip and immediately want to spit it out: do you sit there and keeping drinking it, hoping that in the end you will actually like it? Don't you think that a person who has imposed himself in a shell is already corrupted by it and the chance is higher that you won't like him as himself when you finally get to him?
I dream all sort of things all the time, thanks to a long imposure of books, movies, history and video games. And I have friends to talk those things over with. But it's harder to find a real person or to break someone's shell to see what's actually inside of him. My point is: I don't want to waste time digging into someone, who's dreams right now are about a flashy car to impress his friends. I might not even like what's in the end. And now I have to go and spend the same time on someone else? I'd rather go look for someone who's already real, who already has a higher chance of me liking his/her personality. Even if I won't I'm most certainly going to have a very interesting conversation.
As a matter of fact, I do. I'll have the drink a few more times in order to finalize an opinion that I know I can stand behind. For example, every time I even have a sip of Jim Beam, I want to vomit. I've tried it multiple times, and have concluded I really don't Jim Beam. But deep down in that person who is getting that flashy car is someone who is very insecure and in need of someone to care about them.
