Hi, my name is George and I was sexually abused by my uncle. Uh, excuse me. That is far more information than I care to know. More importantly, it is far more information than is wise to divulge to people you really do not know. Oh, he might prove to be so after a while, but you can't be certain.
Disposable friends are all the rage.
Today you are just right. I suggest that, if you just have to tell someone your secrets, go pay a therapist and share with him. At least if he divulges your secrets you can take him to court. The fact that someone cannot maintain a long-term relationship says something about his character. The fact that this, in general, appears to be the case with so many people today says something about society in general.
