One might build a wall with wallboard—it works, it is good for most settings and most people. It is a modern way of doing things. It is not like were built 100 years ago or 1,000. It meets the needs. It is possible however to build a wall out of brick, or stucco, or ebony, if we want it to look beautiful or create a particular ambiance, or out of bars or pads if we have a certain kind of occupant in mind. Wallboard is like a Will, and ebony, stucco, brick, bars, and pads are like Trusts: more elaborate and expensive.
