There's no harm in being an introvert. I'm like that too.
But the thing is that in a process set up, one should maintain simple cordial relationships with all the colleagues. Having one best friend is fine.. but one should be professional enough with others.. itna atleast that it doesn't happen that they can't see each other eye to eye.
I don't know what the case is with them or Alice, but from Simran's comment that Alice has her own sweet time on sets, and Shiny saying in that interview that alice also doesn't post with her, she's probably way too cut off.
I'm not judging Alice, I like her too, she is a sweet soul, just stating what I felt and my opinion.
She used to be very cordial and friendly towards them in the beginning. She still is i think, she was sitting with them and talking during one of her shots.I think whatever happened w pallavi and transpired in Bikaner has put her off them
All that shiny and simran have said had v hostile undertones to them. I doubt anyone would want to forcefully insert themselves into an equation just for the sake of being cordial :(
