We won't know that other's wont betray us. That's when trust isn't easily developed upon each other. It is just a risk that you have to take. However, I believe that when someone is being entrusted with other's trust, that person should always do his/her best in order not to betray that trust. There may be others who think that something else is worth more then the trust that his/her companion has granted, but to me..... the most important thing is the trust that other people gave..... for I too seek TRUST within others.
