How have you've been Birdie? Haven't talked to you in awhile!
Awww I'm sorry Birdie. I know how you feel.
I lost my favorite chicken too last year. Her name was Lil Grey. She would always come up to me when she saw me. I would sit down and she would jump right up on my lap and sit down on me and sleep. She was a very cuddly chicken and I miss her so much.
Birdie, I'm so sorry. Animals are wonderful because they love unconditionally which is something that most people don't do. I love my pets so much because they don't care what I look like or if I'm 'cool' or not, they just love me because I take care of them and love them. Animals are trusting and loving, and I know how hard it is to lose a beloved pet.
I heard a quote once that said, "There are some that bring a light so bright.... that the light always remains". I hope the joy and love your cockatiel brought you can always be remembered.
