People never notice anything
as long as you want them to, they just pass by.
And when you take a great length of effort to tell them that,
they always have this wide-eyed "oh i didn't know" pose.
At this point all becomes irrelevant, because you already spilled the beans
and the issue had already became worthless to talk about.
And on the other side, telling people things, makes you lose them one after another.
