I usually find out much later, and possibly never. This is how things were before the internet. We didn't know everything going on in everyone's life.

In the case of major events, my brother usually lets me know, for example the death of an aunt. Everyone close to me knows I don't use FB, so if they want me to be aware of something in particular, they can text or call me.

So you push your avoidance of FB to those that care about you to work harder to keep you informed? Not very nice.
