11 years together
So what if 11 years ago you didn't have a wedding. Everyone has a different beginning of a relationship, and often the wedding day is just a painting day without a dress and a celebration. But who bothers at the beginning to give birth to children, build a house, invite friends proven over the years, and make a housewarming ceremony together with the ceremony, saying vows to each other .... For this, any time is appropriate. And finally plant a tree. Life is good! :)
