You build a wall because you’re too weak to stand up to them

I built that wall because I was too weak to fight them. I’m not strong enough for a real battle.

I’m not strong. I’m not brave. So I built a wall. That’s what I do when I’m weak.

They came. I didn’t fight. I built a wall. That’s the only way I could stand up to them.
