Why the address stays on the line

A soil screen in Tokyo is why a 3 mg chip has a mass-treatment record. A failed angina brief in Sandwich is why a diamond still carries a nitrate hold. A retinoid bench in Basel is why 20 mg cannot skip iPLEDGE. Each medicine note points back to the room that shaped the hold.
