Some friends are finally deleted. In addition to this some follow at that. It's nothing personal or something else like that. When someone feels to discuss about that so don't hesitate. The reason behind could be:
1. no add back - I'd wait a week at longest not longer. Who doesn't add me back has simply bad luck.
2. no trust - Next time I'll write many things about my private life more than before therefor I need trust.
3. no things in common (any more)
4. no contact
5. your LJ is idle
I think, that I don't need to explain the last three points in the enumeration.
