indeed, people change through out times. deal with it. it is not something rare. it is normal for people to change. either their behavior, attitude, thinking, appearance, or any thing. it is normal.
so, just deal with it, go with the flow. because, we cant always say that only other people change, to be true, we also change. even without we realize it.
thus, a relationship may affected by it. but, do not be too judgmental bout it, do not be too skeptical, accept it with open heart.. & the relationship will be just fine. because when u r too deep into it, when u r so over-thinking, that's the problem. the problem that affects your relationship, & the 'changing' thingy is just a side 'dish' for the main 'menu' which is the over-thinking'.
so, in my life.. i'd been into this thing for many times. through many relations that i'd been into. i've learned a lot. this is my outcome. deal with it & go with the flow. until today... i am such a lazy person to go into a trouble. i would rather shut my mouth when im in an uncomfortable situation. i would rather be passive when im not interested in that particular situation.
so... this is life. the more u live, the more u learn.
