My prized, Argentinian goldfish died yesterday. I've never been so heartbroken.

Thank you for the condolences, friend. He used to sing me such sweet lullabies when I was trying to fall asleep. I don't know how I will ever get any sleep at night now.

I can't imagine how much that much hurt. I hope you can at least cherish the memories you had together.
