lost thoughts

someone once told me
the more folds you have in your brain,
the smarter you are.
i don't believe them.
i think the folds are there
so the things and people
you want so bad to forget,
can get stuck and
keep coming up in your thoughts.
i have so many things
i want to forget,
but they are stuck
in those stupid folds.
and i don't understand
how the good memories fade away,
and the things you want to remember,
get lost and never come back.
but the thoughts haunting your brain
are there forever.
