Trust is very important in our daily life. A life without trust is a life in turmoil. So, never lie on someone who trusts in you. Because only one lie you made might broke the trustiness of yourself. What for you want to lie to someone who trusts in you? Is it because of self selfishness? Self benefit? For goodness among the relationship? Yes, in some circumstances we can talk lie for OUR or THEIR goodness sake, but not for YOUR own benefit.
Trust is very important in any relationship family, friendship nor love. Never disappoint your family member who always trust in you, never talk lie or say bad thing about your friend who always taking care about you and never do something to show you lose trust to your lover.
Family- Since you are still a baby boy or girl, your family has a big hope on you. For example, they might hope you want to become a lawyer, doctor, manager and many more. We might be able to attempt what they hope on us, but at less never do something which will hurt your family. Can you imagine if one day you commit suicide for whatever reason? What's your family member feel? Why you want to break their trust on you?
Friends- Friends is very importance for me. I trust my entire close friend and in return they trust me as well. But please don't hurt your friend who put trust in you because they has sacrifice their time, money and caring with you. Never forget the good thing your friend ever done to you even one day you back to heaven.
Love- Of course trust is very important to continue a healthy relationship. It is very suffer for you to maintain a mistrust relationship. For example, you always worry your lover talking with other guy or girl. And you end up keep checking his/her phone outgoing call and SMS. Do you feel suffer to do this? If you trust his or her, what for you want to check his/her privacy stuff? Moreover, if you mistrust your lover, you will keep some secret in your heart because you feel unsafe to share with your lover. For me, I can trust my lover very well but hope she won't disappoint me because the best prove of love is TRUST.
Remember this, trust anyone who be true to you, treat them greatly, and they will show them-self great.
