Slightly different from parallel play, associative play also features children playing separately from one another, but in this mode of play, they are involved with what the others are doing—think children building a city with blocks. As they build their individual buildings, they are talking to one another and engaging each other. This is an important stage of play because it helps little ones develop a whole host of skills—socialization (what should we build now?) and problem solving (how can we make this city bigger?), cooperation (if we work together we can make our city even better!) and language development (learning what to say to get their messages across to one another). Through associative play is how children begin to make real friendships.
The airport building was designed as a celebration of the modern age of air travel, providing a sense of adventure to passengers. Jonathan Glancey, architecture critic for the Guardian described what most people feel about flying and what Foster was trying to achieve. "They just see boring office-like interiors, boring people being bored, buying useless bits of duty free. What Foster says is: 'Hey look, flight really is a magical thing.' His building allows you to see the aircraft as soon as you walk in. It enables you to feel you're up in the air with the aircraft too, it's about excitement, it's about passion."
Glancing west, I closed one eye, held my arm out, forming a line of a protractor with suns trajectory towards the hills behind Portland. The Suns path was an entire valley to the south of its solstice high-water mark behind the foothills of the Cascades. The area's long summer days were careening towards the fall equinox, shedding three minutes per day. Like watching a gas tank shrink towards empty on a remote highway, these slight differences in length of day, indistinguishable when viewed day to day, but substantial when observed weekly instilled a sense of scarcity.
