Yes, it does. It happens even with some of the people I know if I'm not comfortable with them. My movement becomes stiff and my voice becomes shaky as if I'm scared. Some people might wonder what's going on with me if they see me in that state. I sometimes spread my nervousness and tension, and make other people uncomfortable, too. When I try to control my nervousness, some people seem to think I'm angry/grumpy/rude (my serious-sounding tone), which makes them grumpy and me even more nervous. It's a vicious cycle. It makes life very hard.
