You have to ask questions kids if you are not sure.
Yeah I still do this sometimes. I don't always know there is a line because it's like I zone things out and I don't notice that there are people waiting. But if I see people standing, I ask them if they are in line so i will know if that is a line or not for something. I remember years ago I stand in line and this one mother says to me "Excuse me, but do you realize you just cut in front of these people?" and I looked and saw another line of people waiting and I go "Sorry. I thought this was the end of the line" and she goes "This is to let people through" and I go to the back of the real line. The reason for a gap was so people can walk through and I thought that was the end of the line.
Even normal people have asked me if I am in line or if this was a line or not or where the end of the line is.
