WHY PEOPLE THINK THAT THE OTHER ONE IS STUPID?

hi every body its me again. i have a question today who ever is reading this blog.
WHY PEOPLE THINK THAT THE OTHER ONE IS STUPID?
THAT I CAN USE THIS PERSON.
MY POINT IS WHY CAN'T THEY JUST ASK ME DIRECTLY IF THEY NEED A FAVOR.
ok let me give you an example of somebody doing that. i met a guy few months ago on a date. he seemed nice (for a week) then we fell apart, he stopped calling giving excuses that he didn't get my email, phone battery died , i mean things that even a kid will understand. ok i got the point 'he is not into me' i thaught. the problem about me is that i believe in staying friends. i was never mean to him. any way i went my way and tried to forget as if never existed . did the usual deleted him from my cell phone add book, messener etc.. then all of a suddens he throws a 'hi' out of no where today. and i am like surprised. anyway i say 'hi' back and casually he apologises for not calling me. then he tells me that his mom and dad r in town, pressuring him to get merried. i did not understand at the begining. any way after sometime i got why he got back to me.
he wanted me to talk to his mom on the phone. he (i assume will tell his mom that he is in a relationship, ya you gussed it , that's 'me') and to me he is saying all nice things so after the mom leaves and he convinces his mom that he has a 'love life' (fake) she would leave him alone for a while.
any way as i said my point is, why didn't he just ask me for a favor. instead of pretending to be so.. anyway... people if you think somebody is stupid and don't understand all this tricks , they do. i just pity him that's all. pity his mind and low level of thinking..
