red thread?

last time i watch a movie called akai ito(japanese movie)...
akai ito=red thread...
this movie says about everyone have own red thread....
the end of this red thread will chain to another ppl....
no matter what happened this red thread wont break...
this red thread are invisible...
and human being will meet up with a certain amount of ppl only they can meet with this end red thread ppl...
and this is what we called destiny...
i think so la...
but i think maybe some will dint have their red thread...
or the red thread dint chain to anyone....
whatever,i believe another end of the thread are the ppl who i known them as prince and princess...
the 1st met maybe is nothing..
the 2nd met is what the movie known was destiny...
for me...
1st met is nothing...
2nd met is coincide...
3rd met is destiny....
sometime even that the end of red thread ppl passed by us we also dunno bout it...
so,when actually we can saw our prince and princess?
