How shall we say? Silence is a bunch of stars in the night sky, pretending not to be staring at us. It is sitting in bed at night before sleeping, thinking. Or not thinking. It is the echo of a cryptic remark, not properly comprehensible. What did you mean? Did you want to explain further? Maybe not.
Sometimes silence is like a whiteness. But some whiteness-es have a milky texture, some have a faint tint, some are more faint. It is difficult to find a zero 100% whiteness.
It sighs somewhere deep inside.
