AAAAAAAAA
I type
To my friend
I'm happy

AAAAAAAAA
I yell
At my screen
I'm angry

AAAAAAAAA
I think
In my head
I'm going crazy

One letter
With so many meanings
How am I supposed to differentiate?
I'm sad

I can't tell
If people are serious
I can't tell
If people are mad

I can't tell
If we are enemies
I can't tell
If we are friends

It's black
It's white
But never grey

It's one
Or the other
But never the same

AAAAAAAAA
