//"It doesn't matter to you . . ."//

The phrase, "It doesn't matter to you," is used in this poem to exemplify that people can be really depressed but the hides it from everyone else. It is like the "moon" doesn't care about what is wrong, just tries to get past it and hide it. This helps to support the idea that this poem is about trying to hide loss that is huge.

Could also suggest that the speaker addresses the moon purely b/c it won't answer, it's not invested in the speaker's problems. Speaker has to figure it out himself.
