People Who Are Infront Of You

You know, those people in front of you when you're walking in a mall or building or somewhere, and suddenly they stop right in front of you for no particular reason and just stand there blocking your way.   Oh you wanted to go on this elevator?  Well I'll just stop and block you from doing that for no real reason.  Oh you wanted to get into this room? But I want to stand in front of the doorway cause it's pretty or something.  Yeah those people make me rage.
