And ((( mean bad emotions. For example
i'm here)) - i'm happy, that i'm here
i'm here(( - i'm sad, that i'm here
it's better to use ) ( .. in internet writting instead of . (one dot), coz dot means that u dont have any emotions now.. it's like order to do something))
gimme this. - i dont want to hear that u cnt, simply give me this.
i'm at home. - i dont have interes to write u, that im at home now
i'm at home.. - n i dont know what to do or i'm thinkin about something, want but cnt say more
i think, this is bad explainin, but u can see, that we use not only brackes for emotions ))
