Depending on how the contract is worded, small claims court may help. If it is just a generic IOU not stating what the loan is for or how it is to be repaid rather than a promissory note, it might not hold up as substantiating evidence.
ask him out, then if he says no he doesnt like you like dat
He doesnt return calls, he doesnt say he will do what he says. He maybe interested but he wants to continue to have his options open. He probably likes you but he doesnt want a relationship. He wants to play the field. He wants to be able to date you, be with you, and others too.

In Guardian Signs, there are no options for a friend Pokemon. You are simply given the Ukulele Pichu from Dolce Island early on in the game and you're stuck with it. A better friend Pokemon system, in my opinion, was in Shadows of ALmia where you could choose between a variety of Pokemon.
  In case Engineer A signs the contract but later discovers dangers to the public, what will be the ethical dilemma facing the engineer? In this case, what are the options available to the engineer?
ANYONE can type a contract. If the wording of the contract is "legally sufficient' the responsibility for carrying it out, or performing its requirements, becomes that of the person who signs it.
That person would be the attorney-in-fact under a Power of Attorney.
The main parties to a contract are the people who sign the contract. Each party that signs the contract is bound by everything written in the contract.
When a person signs a contract to rent a property
Your signs have nothing to do with whether or not he has feeling for you. If he says your his bestfriend, he probably doesnt have feelings, but it also depends on how he acts towards you.
There aren't really any signs. You just have to ask your friend.
Yes, the contract is void if the wrong person signs it. In order to be in a contract you must have standing.
