Hmmm.<p>Sorry. :-)<p>I do this sometimes when in a conversational tone say on Slack or IRC to show I&#x27;m actually thinking&#x2F;confused by the direction the conversation has taken. I think this is better than the person I&#x27;m interacting with thinking I&#x27;ve just bailed.<p>This is not the same as, uhhh, me, uhhh, like, uhhhh, putting filler words into, uhhh, my writing.<p>It is used to enhance the communication by making it more representative of a good conversation, as opposed to using filler words.
