Am I like a credit card,
my mind the magnetic strip,
or are my memories more,
like a pin and chip.

To access me you need the code,
and it's a secret after all,
if you guess poorly,
its me you will have to call.

Don't try to read my mind,
it's locked up tighter than a vault,
if you get stuck trying,
it's really not my fault.

So imagine if your stuck
just trying to get inside,
if I let you in the madness,
you may well lose your mind.

So stick to what I post,
that's free for all to see,
I keep that other stuff locked up,
to protect your thoughts from me.
