The well spring of life is water. Humans are mostly water and we need a steady diet of water. Without water we will die. So it is a wonderful experience as you dip your beak in the well spring of life.
If a man meets a woman who is maintaining a quiet pleasant oasis, he might decide that this is the oasis he likes to dip into. For some men they might want an oasis where no one else has taken a drink. The keeper of the oasis is saving it for a perfect beak man. She might like some one with a gold plated beak. She might like someone with a large beak that can suck up excess moisture in her oasis. All beaks are not the same.
With twins you have a problem. They each have their own oasis. They do not like to share their oasis with each other. If one twin has a beak master the other twin will deny her twin any beaking rights. The good thing about twins is they are so close that they both agree that this is a great idea.
Other beaking issues that can cause problems; are if one keeper of the oasis says "No more twin beaking for you, you are a dirty birdy." This can create problems for the thirsty pores of the beak meister. What is the strong aviator going to do with a soft waterless beak? The reason stated for no more beaking is, "I like your beak and no other beak in my oasis so therefore to endear you to me, always come to my oasis for a wee drink."
Non-beaking twin, "I want you only beaking in my oasis so I'm denying any beaking rights to you to show you how much I want you to beak in my waters."
