Valentine's Day has been celebrated with many different traditions all over the world since it originated with the ancient Romans.

One Danish tradition is to give a card called the "lover's card." It is a transparency, which, when held up to the light, has a picture of someone handing over a gift. Another Danish tradition is to send pressed white flowers called Snowdrops. Danish men like to send a gaekkebrev or a "joking letter." The sender writes a rhyme inside but signs his name with the same amount of dots as letters in his name. If the woman guesses the name of the sender, she is rewarded with an Easter egg later in the year.

In Japan, there are two Valentine's Days. On Feb. 14, the females give gifts to the males. On March 14, which is called White Day, the male has to return the gift he received on Feb. 14. So basically, the females get to choose their own gift. Chocolate is very popular, but most believe that store-bought chocolate is not a gift of true love, so they make it themselves.

In Korea, there is a third day, April 14, for single people. This day is known as Black Day, and people get together and eat Jajang noodles, which are black.

In Taiwan, Valentine's Day is celebrated on Feb. 14 and July 7. Men purchase a bouquet of roses and other flowers. According to tradition, the color and number of roses carries a special message. One red rose means "an only love," 11 mean "a favorite," 99 roses mean "forever" and 100 roses mean "marry me."

In Mexico, men go underneath the window of the woman they love with a Mariachi band. The man and his band sing romantic songs to win her over.

In Scotland, the traditions are similar to those in the United States: various shops are decorated; restaurants and hotels offer specials; and people make cards and give each other gifts.

Neha Zamvar, a 14-year-old from Scotland, says "I don't really have a lot of traditions -- we get each other gifts and we go out. I personally love Valentine's Day; I'm a sucker for the whole love thing."

Here in America, teenagers celebrate Valentine's Day in different ways with different traditions, and they have mixed thoughts about the holiday.

"I think everybody overreacts because every day should be special, but it's a nice day to spend with friends and family," said Megan Podgorski, a freshman at Orchard Park High School. "My family usually exchanges gifts before work and school and have dinner as a family at night. It's just low-key and fun."

Caroline Duszynski, a freshman at Nardin Academy, said, "My family just exchanges little gifts, and then my parents go out for a fancy dinner, just the two of them."

"My family has a unique tradition for Valentine's Day," said Lizzie Kozoduj, a freshman at Orchard Park. "Every year, my dad buys my mom a heart-shaped pizza. It's really romantic." Waverly Colville is a freshman at Orchard Park High School.
