Can't Know - People Change Lyrics

He looks just like me
I guess you've got a type
And even though it's hard to see
Moving on is your right

But maybe just think of me
Just once or twice
When you share my darkest days with the world
Who gave you that right?

So I write this song for you, kid
I hope she makes you happy
I remember those days too, kid
But our forever has run its course, of course

Write your love songs now
While the mystery is still alive
Just remember to keep yourself, kid
And don't be scared to say goodbye

Because I've come to know
People change

I'm not really sure if
People change

How do you know if
People change?

I guess I just hope that
People change

Or do they?
