Walk under a ladder, seven years bad luck.
Step on a crack, break your mothers back.
Rain on your wedding day? Good luck, good luck, good luck!
Superstition has it; rain on your wedding day signifies the cleansing of bad memories or tough times in your past, for a fresh start to the next chapter of your life. Rain washes away old debris while providing life to grow.. like that family many newly weds hope to create.
