I can't pick just one option from the poal, so...
I trust my wife with pretty much everything. There are some limits, but we haven't run into them.
I trust my parents with a lot, not quite as much as the wife, but close.
Family as a whole...some I trust a lot, some I wouldn't give a dollar for a Coke without expecting them to spend it on crack (literally).
Friends, I have some that I trust quite a bit, some that are more casual. Can't narrow it down more than that.
