Hmmmm Do u use tht word of infinite length??

I normally say "Mmmm" when I have nothing to say about what is said or to show a sort of fake interest and I want to move on. I also use "Uhhhhhhhhhhhh" as a space filler.

I have the habit of using such words. I use hmmmmm sometimes Yessssssss.. It's like giving stress and saying things in a firm way,atleast I use it only in such context. To be frank I have harldy noted this aspect while I write responses Will make a closer observation and update you the things!!
