That's gold hahaha, nearly fell on me chair laughing lol. Reminds me of my first missus here. Saying no was like a red rag to a bull. I remember after two years her saying..."so when you say no, you mean no right?" like she had just understood the concept. They all seem to be a little (or a lot) contrary. Sometimes seem to go out of their way to do the wrong or illogical thing.
By the way you can't just give them seed but they are pretty hardy and easy to look after. Sweet little guys too. Can buy a special seed mix and pet shop....and as well as that fruit and veg....they are a tropical bird so anything fruit / sweet like mango, longan, corn, broccoli, Cauli, ....try them on most things you'll soon know what they like. Other than that clean freshwater every day and try nd keep their cage nice and clean.
