My budgie is dead!

I found him yesterday.:'( He was 4 or 5 years old.I feel sad of course! His name was mr Darcy because I love that character in Pride and Prejudice.RIP my lovely budgie!
I'm thankful that my parents' dog Nellie is still with us!! She is my best friend! <3So we get maybe 2 years more with her.I hope so!
