So I went to eat at my dad and his new wife's today. My grandpa was there. After dinner I was walking around the living room and my grandpa asked if I was nervous about something. I said no. He said I must be because I was pacing. Does pacing always mean one is nervous? I pace all the time because I like to be moving rather than sitting still. But I never feel nervous when I pace. Do you think I am sub-consciously nervous and that is why I pace? Or can one pace without being nervous?
