So Obvious

I was played for a fool
Gullible as I could be
To what the world seemed to know
But I couldn't seem to see

Sweet words can fool you
'I'm being honest' just a line
You can end up being used
By that 'honesty' in time

Who do I direct my anger at?
The fooler or my better sense
As helpless as my heart's always been
The wound opens up again

Helpless heart but not helpless mind
It will protect me this time
People walk in, walk by or leave
But I'll never again so easily believe
