Long Distance Friendships

Quantum mechanics have shown that two sub-atomic particles, once they have interacted, will remain correlated even if they are separated by a billion miles.

I think this is so much like friendships.
Especially since we are all going to different parts of the world now.
I hope our friendships will never change.
Even if we don't get to hang out as much as we used to.

So just like the principle of resonance, we don't have to be physically close to continue to vibrate at the same frequency.
