Here's a best friend "acceptable" and "unacceptable" poll thread.
Basically, what you deem acceptable and unacceptable for your boo to do with their best friend.
(I didn't gender this so it would be inclusive)

Best friend sitting on your boo's lap

Best friend sharing a bed with your boo during a sleepover

Best friend wearing your boo's clothes to bed during a sleepover

Best friend going to bed in their underwear while on a sleepover with your boo

So you meet your boo and best friend have normalized kissing each other on the mouth (small mba), you cool with it?

Ayt so bestie had planned a baecation but gets dumped last minute - non refundable things. They ask your boo to go with them instead, you cool with it?

Ok. So quarantine is over and your bestie and boo wanna binge drink. They end up going on a 3 day bender where they just drink, catch up, play bops, vibe out and sleep at one of their houses (with other friends though). You cool?

It's your boo's birthday and bestie plans a surprise party. You're obviously invited, but never consulted on any decisions. (They've been friends way longer than you've been together)

Boo tells you that bestie sometimes uses their bed to do sex with their flings (they can't do it at home because parents). How you feeling?

Bestie calls your boo in the middle of the night crying - they've just been dumped. Boo leaves you in bed to go talk to bestie on the phone for hours - that emotional support, You know? Cool or nah?

You cool with boo having a spare key to their bestie's apartment?

(SURELY this one is ok)

Boo's washing machine is broken and they haven't really gotten around to fixing/replacing it so they do laundry at bestie's place every Sunday, cool?

Let's circle back to the vacation thing.
They plan a friendcation together. Nothing hectic, maybe like one weekend. You cool?

Are you cool with your boo's bestie knowing their debit/credit card pin? (You know it too)

They have monthly dates to catch up, talk, reconnect. Nothing hectic. A lunch nyana this month, brunch the next month. You cool?

How would you feel if you found out they got matching tattoos before you were in the picture?
I mean you obviously can't change it but

How would you feel about your bae buying their bestie a gift you saw them sbwl on the tl? (E.g. a handbag, watch, cologne)

You cool with your boo and their best friend having nicknames for each other? Every time you ask your boo where they came from they just laugh and say it's an inside joke

Ok I'm running out of questions.
How do you feel about your boo being their bestie's ride home from the club? Surely that cool right?

Scenario: you go to the club with your boo, THEIR Bestie and YOUR bestie - your boo is the designated driver.
Drop off time comes, and they (your boo) insist that they drop you and your bestie off first because the route makes more sense.

Ayt I think I'm done .
Thank you guys for participating.
But remember, us best friends are not the enemy.
