Everyday is a very broad term one I find myself using alot. Everyday life, everyday stress, everyday object, everyday action. I use the word everyday to convey how it can be found in the world commonly from day to day.
I covered the everyday object in my dissertation which I called ideas over objects. It may not seem relevant to my work but it does have an aspect of it. I use toys and balls which may not be an everyday object for adults (teachers and parents excluded) but is an everyday occurrence for children to play. I want to someday bring play into the everyday life of adults.
