My parents didn't tell me. My sister and I came home one day and mom was gone. By the time we found her a week later shacked up with some man it was pretty obvious.
I was 14 and didn't have time to dwell on the emotional aspect of my parents were divorcing. It was all I could handle to take care of myself and figure out where I was going to live because my dad was sick and unable to care for himself, let alone a teenager.
