Welcome Back lyrics

I don't know where you are tonight
But something tells me
That you're not doing all right
Well I don't need to hear you say
That you love me everyday
As long as you're right by my side
[ Lyrics from: http://www.lyricsmode.com/lyrics/h/huntingtons/welcome_back.html ]
I promise I won't stay up late
I won't get sick, I won't get worried, I won't wait
For you to come back in my life
Or stop my own to make it right
Yeah I won't tell myself that lie

But when you come knocking at my door
Looking for some slack
Don't worry baby wherever you are
Cause I'll say
Welcome back

You never call while you're away
Just wanna hear your voice say everything's OK
You've got a habit when we shout
To stick your foot inside your mouth
And you know this is killing me
