Nathan was your youngest son. His siblings were treated more fairly than he was. So he never really communicated with you much, nor his siblings. You and his mother/father split up a few years ago.

You were all eating dinner, you noticed him not really touching his food, and his eyes were red and puffy, he was definitely on something.

“Nathan, why are your eyes all red and puffy? You look like your on drugs for f*cks sake.” you sigh.

he was on drugs but, he never admitted it.
