Angela says in an episode, that "There's so many ways to be connected to people."
And we just can't realise, how many there really are. When someone seems to lose us, or we seem to lose them, they kind of grab us, and don't let the connection go and disappear, but it also depends on us.
We do not pay enough attention on caring about each other, cause 'we think...'. But we don't do it right. Because at the same time - we feel. Something else. And ours feeling always seem to be more real, and lifelike than any other... It's kind of an instinc we got from nature. with the only difference that we use it in our relations and not to protect our lives - not in it's phisical meaning. but we do protect it in the mental way.
