Trust.

Friends always will support you, until you get into a fight with them and then all of a sudden all of their opinions about everything in your life change and suddenly you are doing everything wrong and are a terrible person. That is why it is so hard to trust people now a days because you never know what could happen, all of a sudden you could hate each other and your friend could use all you have told them against you. Having as Best Friend and trusting them with all your secrets can always back fire on you.

Be careful who you trust. Trust is like love, you have to be careful who you give it to because you can always get hurt when you put yourself on the line with friends or with love. Walls are good, walls are safe, and walls will protect you from getting hurt.
