ok I see, its ok to not know everything about the others that are with you. Im going to word sense of agency in the singular wording so you may understand....

sense of agency is...

you knowing how much control you have.....example you know you are able to post on psych central but you do not know what the others do. you posted that you are most active outside.

you are aware of yourself and your surroundings... example you know you have a computer or have access to a computer, or you have another form of internet access. if you were not aware of this and not aware of psych central you would not be here on psych central... being aware means you know whats going on around you. some people call being aware, being alive.

you have functionality... this means you can move and do things. you can get out of bed, turn on the computer and type on the keyboard. you can eat, you can drink, you can ...what ever you do physically...go to work, play, talk on the phone, watch tv and what ever else you want or can do. your job, purpose reason for being and doing what you do.
