It's the same as in any other walk of life.
School ... some become buddies, others not.
Neighbours, workmates, sports, hobbies etc all the same.
No different with SPs', though not as frequent
What they show on their SP social media accounts is only their SP persona.
I suspect that pretending to be friends (or more) on twitter is a good way to gain some visibility.
Whether the friendship is real or just for show is probably none of our business.
Of course they hang out
Have pillow fights in lingerie
Fuck each other’s brains out and sometimes invite a random dude
Their life is like real life porn
Some do and some don’t. I think there’s two pretty big issues that make it hard to just become gal pals, like some co-worker in the office or something.
Some do, some done. I was regular of 2 whom met at the work place and then became friends and roommates (that was fun), and were also friends with a couple other girls.
