Trust is a two way street.. Usually a person has to earn anothers trust.. And yet sometimes mistakes do happen in trusting someone.. If it was a major mistake, we usually tend to take longer to forgive the other person.. But, if it was a minor mistake that is for you to decide.. Because you need to determine if it had been something that you might have said or done (not intentally) would'nt you want the person to forgive and give you another chance.
