Do you let your birds out of their cage?

My sister-in-laws mother has several birds in you her house. I have been over to her house and must admit the birds can be quite noisy! Sometimes, she lets them out of their cage, while I am over.

This kind of gives me a fright! It reminds me of when I was young and had a pet parakeet. When I would let her out of the cage, she would dart toward the windows. I was always afraid, was going to hurt herself!

If you have a bird, or know a friend that has one for a pet, do you or your friend let them fly loose?
