I'm 5' 8" and 140 lbs. I rarely have a deep booming voice (I can if I really mean to). I am usually a VERY quiet and soft spoken person.
I've been told that I can be very intimidating with just this intense glare that I seem to produce, from time to time. I think I know what they mean but I'm not really sure. I've been told that more than a few times, even though I'm never really aware that I've done it.
