but hor, i dont know what do you mean by private session.... how
private is private? Just intimate chats? If it's like that, i dont
really care if a 3rd party hears what im sayin.. 
hmm for me, if there are extra seats, whether if im alone or not,
i'd just let the person sit lor. But he/she must ask me first "Hey
is this seat taken? Can i share with y'all?"
Basic courtesy i value that a lot.
Just normal chats la...sometimes might get intimate or too
embarassing to be heard by others...I can't really control the way
our conversations go
