It depends. If someone is smaller than me, they have a tendency to run away, and clear the area when I get mad. They can be taller it doesn't really matter.
Other people break down and cry.
Normally I don't get mad unless someone has really done something to piss me off.
If they were born and raised on the street or if they've done time... I don't mess with those people, they are way more "real" than I will ever be.
