Do u think some things,animals,gestures,etc can bring bad luck?I know persons who are afraid to do something because they think somethink bad could happen.Some ones are afraid of black cats,others don't go back from where they left,or don't drink water before they live home.I'm not a superstitious girl and i don't go by that.What do u think?
