no, it's actually almost a universal truth.
(and thoes are pretty rare)
but here's why:
if you DO trust someone, they don't need to ask for your trust, it's already there.
if you DO trust someone, and they have to ask for their own reasons, then there is a reason in there somewhere, perhaps in their own mind; why you wouldn't trust them. perhaps a reason you don't know.
if you don't trust someone, and they are trying to talk you into an activity or idea you don't want to do, and the only way they can think to get you into it is for them to somehow MAKE you trust them... then ther's an alterier motive. there's got to be a reason for their enthusasm, a reason why they need your trust, and even if that reason IS altruistic, really; you sould proceed cauciously, if at all.
or, if you don't trust someone, and they don't need your trust to go forward, they can tell you as much. if it's not necessary, you wouldn't ask for it.
if you are driving down the road,and you run out of gas, and someone else pulls over do you ask them for a cup of sugar? no, because you don't need it. and if they didn't give you a cup of sugar, would you still get a ride from them to the gas-station?
the sugar isn't needed. if the trust isn't needed, they wouldn't ask for it.
if you find yourself on the flip side of that argument, asking for trust won't get you anywhere. if anything, it'll just make the people involved less likely to trust you. what you should ask for, is for the people in question to trust themselves, and to make a command decision if they want to be involved or not. if they decide not to trust you, at least you offered to help. some times people need to make their own mistakes, and learn from it.
so, anyways, don't trust me on this: listen to the logic and trust yourself.
at any rate, I can't see a situation where it WOULD be a good idea to trust someone who says: "trust me"
you may have to go allong with them if the situation warrants it, but I'd suggest going cauciously, if at all.
