I can diagnose your sick budgie and you too CBBB, and what's more I don't need to see either of you to do it! First your budgie- he's lonely and depressed because his Daddy spends all his free time on the Cyprus Forum getting into cyber-rows with people. "Flame mail" as it's commonly known of in the UK IT sector is a convenient and anonymous way of venting one's life frustrations with an imaginary enemy on an internet forum. (Refer to international dialling codes to see CBBB in full flow CBBB)... Ironically though people who engage in flame mail are often charming and funny in real life!
Second you, 2 years with respiratory illness having numerous tests in the UK. Did you know you can contract 2 lung diseases from owning a budgie? One is called "bird-fancier's lung" and the other psittacosis. If you really do own a budgie then you might have contracted this, it's usually overlooked because doctors forget to ask if the patient owns a bird. If you don't do the right blood test for this infection all the expensive tests in the world won't show it up. Incidentally, psittacosis can also affect the brain when it is not diagnosed and treated promptly - so I'll forgive and forget.
Affectionately, Titsup
