Associating , ppl and sync

i always feel that we were intended to be ,and remain, as we were at the time of our birth, very alone in the midst of five billion of our species.
what am i trying to say? very difficult to put these thoughts in an organised prespective, for the thought process is so fluid and consistently shifting.
Of the millions of ppl that exist surrounding us,we choose a few that we want to associate with, at varying levels of intensity, or at the other end, life throws some at us, but it is extremely important to take a moment and analyse, that do v actually hv some sync with the person in question?
I think the world is a large jigsaw puzzle, and v are all small pieces, each essential to the whole picture, yet amazingly unique in our own ways,and that u just can't take any two randomly, and expect them to fit. This is turn explains why some times the very best of ppl, with the best of intentions, don' just fit together.
where is this leading? i myself don't know, am just typing as i think.......bt the idea is to say that it is necessary to analyse and be with ppl who bring out the best in you,and have an inherent sync with you.i mean just think about it , have u ever noticed that with some ppl u r so comfortable, yet with some, who u think r ur closest, u r perpetually on an edge?analyse this thought,u'll be surprised at the outcome.
personally to me, this point became relevant after i noticed it in some of Osho's writings about being with someone who makes your soul come alive, and further developed when i went back in time , and analysed some very painful moments of the past.
i think the idea is that of the countless ppl around u , u had to choose those very few u wanted to call ur own, take the pain to choose those who like u , and who r capable of being liked by you, for who they are....
relationships are like speaking a language, if i am conversant in russian, and you in german, and there exists no common ground for us to communicate....wat r we gonna talk about?and wat level are we gonna connect at? the same goes with ppl, there has to be a sync, that connection, to u to connect at that amazin level.....and if there is'nt, be assured that sooner or later , u will realize that this one relation , that u assumed was special, is like the countless other meaningless one's that we accumilate , over time, based on all the wrong motives.......

a lot more can be said on this, but right nw i am blank...................................
