Automatic Blunt Rolling Machine Remembering Sunday (All Time Low) Lyrics Question?

Remembering Sunday (All Time Low) lyrics question? - automatic blunt rolling machine

Sings in the song, automatic "Remembering Sunday" by All Time Low, Loveletter Juliet Simms' part of the song. I wonder if they even sang the text below, right on the way:

I will not (sorry)
I did something so terrible
I'm terrified to speak (I'll call, I'll call you)
But what is expected of me
I'm confused, I'm going to blunt the rain is just (You're Driving Me Crazy, I)
Wash my hair ...

I know she sings the words in brackets, but what about the rest? It's more like a song Guy, but in all the places I visited, they say that they sang. Is it real or is it Alex Gaskarth or another member of ATL song?

It is a lame question, but hear me for weeks, and every time I hear the song that will always know who sings.

Thank you!
