@Ducky When you have your trust broken many times, it gets harder to trust anyone one anymore, isn't it so? But if you meet someone trustworthy finally, how will you be able to let them in?
@Renkon there are many such people who just do not know how to deal with people. They invariably pounce or jump on by assuming (blind trust) and expect the other to withstand and if they fall, they blame the other as untrustworthy.
@Renkon not consciously but subconsciously. Sad state has been created by many staying gaurd and shunning advances of people who approach. Many just hurt people unnecessarily by acting too smart. Thus many we see are in an irate state.
