Potential Friends

Providing yourself with shelter
A shield from the sword
The pen is mightier
Than the sword
The tongue is twice as sharp
If words could kill
If looks could kill
Something will
Come out of this
Even if it the lesson
I should have learned years ago
To stop throwing it all out there
To stop showing that I care
To stop caring
To the extent that I care
To the extent that I share
This is why I scare
Potential friends away
