Very strangely... my goldfish has just died. There are only four possible reasons that I can think of as to why "Frankie" would pick this particular night to snuff it...

1) Depression - Frankie voluntarily closed his own gills
3) Goldfish memory - Notoriously short, he may have just forgot to be alive
2) Kaiser's theory may be correct
4) I simply didn't feed the little prick

Whatever the outcome, I'm not gonna take any chances. I'm taking NCG's advice and I'm gonna spend my last night drinking beer and watching porn...
