Bonding

Bonding

I heard people talked about putting trust into something they admire in their life, for example a friendship. I saw how people change upon a relationship which sometimes it does bring harm more then what they hope for. I had encounter a situation in which when A and B are together, they enjoy the time so much, sharing everything, support each other and show how they appreciate the bond they have. But when B comes to C, it turn to be otherwise when they talk about A, nothing is nice. Is it worth to put a trust? Share your view.
