How feelings changes with the same person....

actually some of readers will think that i am a viable person whose feelings changes with the time. But it actually happens with us. Let me tell you small "sher" related with small story.
There were a person named as Ayan,whose best friend was a girl named something(actually i cant remember her name now). She loves him so much and he also likes her but not actually in love. But he loves to flirt with her. Once when he was flirting, she asks him that we are together from our birth then why you flirting with me in this age only.
There is a "sher" by Mr. Ayan......."Dil to tumhara tab bhi wahi tha,
                                                        Dil to tumhara ab bhi wahi he,
                                                        Fark to sirf itna he ae janeman,
                                                        Tumhara dil tab tna katil nahi tha"
Actually i didn't get its meaning instantly but then after i realize it's meaning.
As we are being mature with age, the person's in our life also changes and feelings off course.
It actually happens with us. When we were in school with some girl but due to absence of maturity we were not that much attached with her. But as the days passes we are getting attached to her and we even cant notice that with that attachment how we are falling in love with that person.
So its not a judgmental thing to think alot. But it's the only state of mind which changes according to age and maturity........:-):-)
