"Heartstring" lyrics

If I'd gone where I could have been
Would we be what we ended with
If we crossed at another time
Where would we spend our lives
Does the world really take part
Where you end and I start
Have my best friends been met
I guess I seem upset

That's why I run my mouth around like that
'Cause I know what you know
That's why I run my mouth around like that

Do you still feel too young?
Time it's tough to outrun
Can you catch what it would have took
To check off that notebook
Make it feel as a simple thing
To pull on my heartstring
I can think of a million times
That you changed my mind

That's why I run my mouth around like that
'Cause I know what you know
That's why I run my mouth around like that
