Stretch out the furrow muscles in your brow because this week's Letters to the Editor is all about concern.

—Caroline Skinner (no known relation) is concerned about the smoke billowing from that crematorium in SE Portland. Specifically, she's concerned about the mercury (no known relation) in dental fillings being incinerated and shot out into the neighborhood's breathin' air. Ah, the cycle of life.

—Our interview with Portland Pearl District Neighborhood Association President Patricia Gardner kicked up quite a bit of concern, too. Specifically: concern that the red tape associated with land use development is being compared to homelessness; that the tax-aided development of the Pearl in the first place didn't involve too much public process either; that a building with a real roof might be a better location for Right 2 Dream Too; and even so, "token subsidized housing is not enough."

—Also, fluoride! (Really, Steve?)

—Alternatively, you could concern yourself with getting familiar with the Portland-developed videogame Gone Home. The choice is yours.
