I feel that you will slip into things you wouldn’t normaly do in “real life” and the repetition of it will make it part of urself and eventually you will do it in real life.
If you can avoid facebook, do so. You will save urself from a lot of trouble. I guarantee it.
You know just like one will text something they wouldn’t say out of their mouth, one will befriend one whon they woulndt in real life. Once ur friends on facebook you may become friends in real life too.
My verdict: the Cons of fb far outweigh the pros.
Hatzlacha.
