ironing board
An ironing board is supposed to vanquish wrinkles but ends up being a portable obstacle in the household. Expand its surface and it immediately asserts territorial control over the room; fold it and it vanishes into oblivion. In use, one may hail it as the pinnacle of convenience, only to resent the toil of assembly and disassembly. The airy truth is the paradox that a device meant to smooth out imperfections ultimately amplifies human frustration.
