I saw another budgie that looked a lot like ours a couple of weeks ago, in a nearby suburb. It was a girl, though, but still, hopefully it means we're slowly but surely getting closer to finding our little buddy. It gives me hope that the little guys can survive, and can be found by nice, caring people.
I know our budgie's out there somewhere, hopefully not too far, and I hope someone nice is looking after him...till the day we're reunited.
