Let's invite them over

I know why you're lonely and I know why you're blue
You're lonesome to see him and you long to see her too
We're not in love with each other we're in love with our best friends
So let's invite them over again
We talk it over and over and we know it's not right
We should stay away forever but we're lonesome each night
Yes we stay away for awhile but we know in the end
We'll invite them over again
We talk it over and over...
