They're only plastic BBs. It was an accident.

只是塑料枪。这是意外。

It's like shooting a sawed-off shotgun from a thousand feet, and getting that one BB through a hole so tiny, you can't even see it.

就一把削短型霰枪射，要从 300 米开外射出一枚，过一个根本看不清的小孔。

That's a lot of years and a lot of bbs. Once they're born, they immediately leave their  family for a life of solitude.

那是很多年和很多BBS。一旦他们出生，他们立即离开家人过着孤独的生活。
