Why'd you have to go and make things so complicated?

uh huh life's like this

uh huh uh huh that's the way it is
cause life's like this uh huh uh huh that's the way it is
chill out whatcha yelling' for
lay back it's all been done before
and if you could only let it be you will see

lay back = chill out | let it be:?To leave something to follow its natural course.

I like you the way you are when we're drivin' in your car
and you're talking to me one-on-one but you become
somebody else round everyone else
you're * watching your back like you can't relax
you're tryin' to be cool
you look like a fool to me tell me

watching your back: to protect yourself against danger

why'd you have to go and make things so complicated

I see the way you're acting like you're somebody else
gets me frustrated life's like this you
and you fall and you crawl and you break
and you take what you get
and you turn it into honestly, you promise me
i'm never gonna find you fake it no no no *

you come over unannounced
dressed up like you're something else
Where you are ain't where it's at you see you're making me
laugh out when you strike your pose
take off all your preppy clothes
you know you're not fooling anyone 你誰(shuí)都騙不了?
when you've become somebody else round everyone else *

come over: come to a place, especially somebody’s house, in order to visit for a short time

strike your pose：to hold your body in a particular way to create a particular impression
