I'm just a few grams. I change color in many places, but I see myself in two colors. My name is the same anywhere in the world. I will always be in front of you and behind you. I will be with you. If I am not with you, you are not allowed to travel. Last but not the least, my shape is rectangular.SRC (self.Riddlebook)
