A cupid is a winged child known for piercing the hearts of victims causing them to fall deeply in love. In Greek mythology this child was known as Eros, the son of Aphrodite, the goddess of love and beauty. In Roman mythology he was known as Cupid, the son of Venus. Cupid is associated with Valentine's Day because of his association with love. It has become quite common to give valentines to others that you care about.
Children often give valentines to mothers, fathers and friends.
Of course not. The best valentines come from the heart. In early days, homemade paper valentines were very popular in Europe. You too can make your very own valentines. With some pink, red and white paper, scissors, glue and a little imagination you can create a unique valentine that anyone would love to receive.
