When you are sharing your joy, you don't create a prison for anybody - you simply give. You don´t even expect gratitude or thankfulness, because you are giving, but not to get anything, not even gratitude. You are giving because you are so full of joy and life, you have to give.
It happens to everyone as they grow up. You find out who you are and what you want, and then you realize that people you've known forever don't see things the way you do. So you keep the wonderful memories, but find yourself moving on.
