A Mercury-Pluto link on your birthday means there is a specific path you must follow over the coming year. The nature of that path will be made clear to you over the next few days, so keep your eyes and ears open and be ready to move fast.

Four is an open door

This is used in the Australian universities, where a full mark is a 7 and 4 is a pass. Refers to a bunch of huslters who never watched a single lecture, winged an exam during the exam block, and walked out feeling relieved. 4 is an open door was a commonly used meme on Stalkerspaces where Anna and Hans from Frozen sing "Love is an open door". Hans is the evil prince Anna decided to settle after the first time she ever met a man.

Hey man, how was the exam?
It was crazy!
Crazy?

YOU:
All my life has been a series of doors in my face
And then this one… just slammed into my face

FRIEND, spoken:
I was thinking the same thing—'cause like—

I’ve been studyin' my whole life to earn that degree
And maybe it’s the caffeine talkin’ or the stress of week three

YOU & FRIEND:
But with you—(but with you, I haven’t watched a single lecture)
We found the strength to wing

And it’s nothing like I’ve ever known before—

Four is an open door
Four is an open door (door)
Four is an open door
With you (with you), with you (with you)
Life could be so much more...

FRIEND:
I mean, it’s wild...

YOU, spoken:
What?

YOU & FRIEND:
You and I were just meant to cram!

FRIEND, spoken:
That’s what I was gonna say!

YOU:
I’ve never met someone—

YOU & FRIEND:
Who panics just like me

Attacks! Attack again!

YOU & FRIEND:
Our mental synchronization
Comes straight from sleep deprivation

You and I were just meant to scrape by!

Say goodbye (say goodbye)
To the comfort of our beds
We don’t need to sleep anymore

Four is an open door
Four is an open door (door)
Life can be so much more
With you (with you), with you (with you)
Four is an open doooooor...

FRIEND, spoken:
Can I say something crazy?
Let’s just slay the pass.

YOU, spoken:
Can I say something even crazier?
I already spent my savings on a retake.

a little wide open

to be intoxicated from alcohol.

Janet had a few too many drinks and ended up a little wide open at the end of the night.
