In a relationship :
You have authority when you can demand someone do something for you. Authority could be due to your position, control, circumstances, anything.
Trust is when you can ask and you know that the person would most certainly comply as long as it is possible and reasonable
Request is when things are tentative; trust is building up but not at the stage where you inherently know that the persons would probably do your bidding, but then could as likely be proven wrong, or the manner in which the stuff is done would ensure that you don’t ask again.
The relationship could be at different stages for different stuff between the same two people -
(Most) wives can -
- demand that the husbands do all the driving,
- trust the husbands to take care of them
- request that husbands cook at times
