Me and my best friend...crazy connections?

my friend and i met 9th grade year and have been close ever since ( almost sisterly)..recently we've been realizing that we have so many things in common. and even people realize it without knowing themselves. for example a random girl walks up to us and asks if we're best friends. and other example is our teachers mix up our names even though we never talked or sat by each other in cl.. and we look totally different (im african american, and she's latino). it seems as though our minds work together automatically. the teachers wonder why we get done with our work so fast when we work together.. even strategic puzzles we solve in an instant. we also realized connections with our boyfriends. for instance both of our ex's turned out to be best friends in the long run. and both of our boyfriends got kicked out of the same school. they are both older. listen to the same exact music. we have different styles but, you can say we accentuate each other. even our teachers say we have a crazy connection going on. sometimes we even speak in synchronization. this may be irrelevant but we have the same phone carrier, were like the only friends we have left that have that phone carrier. also we talk on the phone and we later realize we were doing the same thing before we got on the phone. we act like twins without even knowing. be mindful that we met in ninth grade, lolz we were born on entirely two different sides of the united states.. i have a feeling that if i never met her in high school., i probably would have met her some time in the future...by mutual friends... what do you think this crazy connection could be. because we're really curious.
