I liked this line because such mundane things can sometimes lead us through profound trains of thought. Like with Dickinson's "There's a certain slant of Light" and how a beam of light made her think of death and religion, a whiff of perfume made this speaker think of his self worth and longing for connection and love.

I liked this line because I interpreted it as he was preparing a persona to match the people he would be spending time with. Instead of just being himself, to make others like him he would prepare a "face" that's more likeable just for the validation of others.

This line struck me because it showed that the speaker thought so little of himself that merely making his existence known to the world is seen as him as a disturbance. He contemplates if his longing for connection is worth staining the earth with his identity.
