Trust. Do trust people.
Trust but check the result. Put them on the scale to see who they are.
Example:
My lovely girl wants me, and I love her too.
I said- if we are to be together our bank accounts should also should be together.
She said -. I'm not sure about that. I worked hard to save and now I can't just combine our cards.
True story,. Personally, I would merry her and have a family. But this " money" shearing didn't impress my girl.
After many tears I let her go "by by".
We can only trust people who put as much gold as we are. This is the only way to find or loose a friend.
It doesn't have to be a chank of money as a contribution. But whillingless to give it all on order to succeed.
I'm still looking.
