Brothers and Sisters Day is observed on May 02, 2017. It is a day in which siblings cherish one another. Of course, there may be times you don't like to talk to your brother or sister, but this day should not be one of them. Go visit them and give them a hug, or at least give them a call to let them know how important they are to you. Imagine, how your life would be without them. You may also send your brother or sister an e-mail or even mail them a card or a small present. If you don't have siblings, just act like a brother or sister by being nice to someone you like. Maybe you even have a friend who's like a brother or sister to you. Brothers and Sisters Day may not be confused with Siblings Day, taking place in the United States on April 10 each year.
