For some selected friends, I don't want them to think that I was selfish. And also helping to educate them.
That was your choice. It is sometimes we think about our privacy but guess what, it can also create wrong speculations about your life. It was better for your closest friends to know and be aware of your doings for at least, they still have the confidence being with you. If that never creates any trouble which I think not, they also have the right to know something. That is the meaning of true friends.
