Humpty Dumpty

I'm having a hard time walking this fine line 
I stumble, trip, and fall

Then I get up again 

How many agains do men get

I'm deaf to your definition of appropriate 

Guilty cause of my associate 

Get burned by the fire if you get to close to it 

Are you gonna learn to discern between smart and stupid 

My only use is being useless 

Public nuisance pissing on private property 

I can do anything I want but probably not properly 

Sometimes I can't see the stars shine 

Staring through dusty blinds 

Rusty insides 

You can trust me sometimes 

But I'm only human 

Forgive me if you want

Hate me if you wish

I told you I love you and I don't break a promise
