In Venezuela it is celebrated on February 14, day in which the couple, spouses, and friends, is the day of love and friendship, in which couples in love express their love and affection to each other, their name day is Valentine's Day.
Some people have the habit of giving flowers, stuffed animals, cards and chocolates, among the most common and meeting to share with the closest people. I made a "Tree of Love" with recycling material (cardboard, fabric, tin, mechacillo, palm branch), an activity that I like, to celebrate this event.
Wow, that is amazing. :)
