hello & welcome 
to common sense 101
i am your professor
i go by the name of ne-yo
now i will not sit here n say i kno it all
but i kno enough
and im here to help
so if you take your seats
we can begin
lets go

verse 1:
said well i don't kno what yall been told
but there aint many
house wives that once was hoes
do we normally happen that way
the answer is no
so what u tryna test it for

and so u met her in a club
rubbin on u cus of who u thought she was
she put it on you thats wassup
but now your talkin bout how your in love

well if she was trickin when you met her
what makes you think that she aint trickin now
and if she had a boyfriend when y'all hooked up
what makes you think that she wont mess around

its just common sense
think about it, bout it
think about it, bout it
think about, about it

its just common sense
think about it, bout it
think about it, bout it
think about, about it

girl i don't kno what you dreamin bout
how you are happy
because your with him now

but he left her to be with u
and baby girl i strongly doubt
that with you he gon take a different route

he come n see u every day
smellin like them vicky secret body spray
girl u kno
either he creepin or he gay
baby that aint nothin u need either way

well if he was trickin when you met him
what makes you think that he aint trickin now
and if he had a girlfriend when yall hooked up
what makes you think that he wont mess around

its just common sense
think about it, bout it
think about it, bout it
think about, about it

its just common sense
think about it, bout it
think about it, bout it
think about, about it
