Dave speaks correctly.
I, as administrator, may be a lot of things here on this forum, ANNMARIE, but the etiquette police is not one of them when it comes to decorum. Most of us here lead very busy lives, and are in a hurry and don't have the time to pick and choose our words so carefully.
I agree with Judy, that "common sense" would dictate that you don't leave a bird to his own supervision loose in the house when you are not home. These are our opinions based on our experience, research, and we like to warn new bird owners of ALL the possible dangers that can lurk. IGNORANCE IS NO EXCUSE..... we are here to help and voice our concerns when we feel it is needed.
As far as the "two year old" comment, no you wouldn't "cage" a two year old, I don't see where Judy said you would, BUT you would make sure that they were supervised at ALL times, for their safety as well.
