honestly
literally
"I dont.....
the first 2 words are nonsense word fillers, they dont make anything you are saying more clear,,,(rarely "literally: does)
"I dont,,," usually followed by some personal issue,
I dont understand
I dont know
I didnt know.
more word fillers, say the next sentence first, no one cares about your personal issues
"I'm not gonna lie here, I dont know if this is a good post for this thread, Honestly"
