Southern N.H. Regional Med. Ctr., 141 N.H. 589, 590-91, 688 A.2d 565, 566-67 (1997) (brackets, quotations, and citation omitted). We look to the plain meaning of the words Used in the statute when possible. See id. at 591, 688 A.2d at 567. Nevertheless, we do not assume that the legislature would enact statutory language that would lead to an absurd result. See State v. Kay, 115 N.H. 696, 698, 350 A.2d 336, 338 (1975).
