I envy Meredith-Cristina relationship in Grey's anatomy or Harry-Hermione-Ron's in Harry Potter series or House-Wilson complicated bond in House md.
I envy those characters as after 2 decades, I havent really found that. The one that really close to you that you can read each other mind and do everything in the world without any hesitation. I missed that one person who made me feel alive and true. She is my Cristina Yang if I were to be Meredith Grey. I once had that person and I let her go. And that was my greatest regret.
If you ever have someone like that today, never let her go, ever. Because as many said, lightning never strike twice. Have no regrets, live your life to the fullest.
