This is a bad mesh.
Here is what is wrong with this mesh:
Mesh has 1554 non manifold edges.
Mesh has 255 duplicate faces.
Skipping face direction check because of positive non manifold edge count.
Important things to consider with this mesh:
Mesh has 124 naked edges. Although this does not necessarily mean that the mesh is bad,
naked edges can cause problems if the ultimate goal is STL output.
Mesh has 3075 pairs of faces that intersect each other. Although this does not
necessarily mean that the mesh is bad, it can cause problems if you're doing mesh boolean operations with it.
General information about this mesh:
Mesh does not have any degenerate faces.
Mesh does not have any extremely short edges.
Mesh has 2 disjoint pieces.
Mesh does not have any unused vertices.

my flatmate one day told me :
"Angela, you are such a dreamer"
then I answered :
"If i don't dream, I cannot be in here now."
If I keep dreaming, I will not be in here.

I got a new brother named Mario Lee who know how to make 咖喱吉烈豬，海鮮燴飯。Crazy...
God keeps adding impossible faith into our love, that is how we survive, and how I survive in this insane city.
I felt a circle today.
A person sent you a telepathy message; but then he sent an email and asked you whether you got the telepathy or not.
Yes. Communication today is getting strange.
I almost laugh because I am confused whether I should reply by email or telepathy.
Before anything I should get some energy, back to patient bed until the sun rises.
1. Put out your bread on the face of the waters; for after a long time it will come back to you again.
3a. If clouds are full of water, they pour rain upon the earth.
7. Light is sweet, and it pleases the eyes to see the sun.
10a. So put away trouble from your heart, and sorrow from your flesh;
10b. for youth and vigor are meaningless.
