Sans:
I made a promise to a friend that I don't really know
But since you're here I'll try to be nice and let you go.
You've got to watch yourself and all of your decisions now
'Cause I'm just sitting back, relax, enjoy the show and how.
Everything you do will change my mind about you
If you go hurting others just because you want to
You don't really want to get on my bad side
If you do, then you are gonna have a bad time.

Why should I
Try so hard to keep you safe?
Well I guess I
Can spare you this time since you seem okay.
(Can spare you this time since you seem okay) 

I never said that I wanted to stay down here
Surrounded by crazy peeps, that want me to disappear.
I don't even know why you try to keep me alive
I mean c'mon no one would care if some wouldn't survive.
Now listen Sans, what keeps you here while you have so much to give
Are you sure that you so [bad word] DETERMINATIVE?
Oh yeah sure, im gon' have such a bad time
Imma just casualty leave this part cus there's nothing else that rhymes.

Why should you
Try so hard to keep me safe?
Well I guess I
Can spare you this time since you seem okay.

I guess you're my friend.
We had our good times
But something about you
Doesn't feel right.

Why should you
Try so hard to keep me alive?
Well I guess I
Can spare you this time since you seem okay.
