You i do not understand

You i do not understand
you say you care but you don't
you i do not understand
you say you'll fix it,you wont

you i do not understand
you make me laugh,then cry
you i do not understand
say your sorry,its all a lie

you i do not understand
you say your my best friend
you i do not understand
that you'll be my friend till the end

you i do not understand
how you can be so mean
you i do not understand
i just don't understand...
