[Verse 1]
I mop the mess you made
Before I even eat
You slam the door, you sigh
Then leave it all to me
You say I'm being cold
I just call it grown
I pay the bill on time
You still want to be held
[Pre-Chorus]
I learned to bite my tongue
You learned to make a scene
I count the things I need
You count on me
[Chorus]
Why you act like that?
Why you act like that?
Mid-twenties, throwing fits
I'm the one who handles it
Why you act like that?
Why you act like that?
I grew up fast, that's that
I'm the younger sister, but I'm not your match
[Verse 2]
You leave your shoes by the sink
Your hoodie on my chair
I clean the whole apartment
You say that isn't fair
But when the rent comes due
And somebody has to stay
I'm the one with the plan
I'm the one who can make it
[Pre-Chorus]
I learned to bite my tongue
You learned to make a scene
I count the things I need
You count on me
[Chorus]
Why you act like that?
Why you act like that?
Mid-twenties, throwing fits
I'm the one who handles it
Why you act like that?
Why you act like that?
I grew up fast, that's that
I'm the younger sister, but I'm not your match
[Bridge]
I'm not your mother
I'm not your fix
I won't keep shrinking
Just to hold your script
You can be the big one
If you act like it
Until then, I’ll stand here
And say it again
[Final Chorus]
Why you act like that?
Why you act like that?
Mid-twenties, throwing fits
I'm the one who handles it
Why you act like that?
Why you act like that?
I grew up fast, that's that
I'm the younger sister, but I'm not your match
