How is it?

How is it
that i fall so fast
that simple happiness
just cant last

how is it
one minute i like you
but after all the rumors
i don't know what to do

how is it
that i can look good
but i am not happy
like i should

how is it
you left me
without a goodbye
i just don't get why

how is it
i tend to get sad
but you never expect
that i feel bad

how is it
i can be so happy
but the next moment
i am so sad...?
