My boyfriend's 14 year old tried to run away

My boyfriend was arguing with his 14 year old and his 14 year old said hes done and leaving. So he packed his stuff and says

14: I'm out!

BF: Ok.

14: You'll never see me again!

BF: Understood

14: You'll miss me

BF: Won't know until you leave

14: K... Almost out the door... Bye dad!

BF: Bye Philip.

My bf's son left and an hour later came back asking what was for dinner. My bf had cooked shrimp scampi. My bf said ?"Room clean?" His son sighed and said yes. Then my bf handed him his dinner. An hour later they were watching Wall-E together. Father son relationships are strange lol.
