Magnum, P.I., Season 7

Magnum:
[narrating] A cogent note about Walter Pidgeon, not the actor, my cousin Rainy's pet bird. One summer, Walter got out of the house, onto the deck. He would have flown away except there was a glass partition he couldn't get through. He kept trying and trying, but he kept hitting up against the glass. Now, two feet to the left, and two feet to the right, the partition ended, but he couldn't see the obvious, that there was a glass wall in front of him. The difference between me and Walter Pidgeon was I had finally seen the wall that Frank Foley had thrown up in front of me and I was taking two steps to the left to get around it ... [short time later] ... One last thought about Walter Pidgeon and the "glass wall". I'd always wondered what would have happened if "Old Walter" had gone around the partition and found his freedom. What would he have done with it? Maybe it was better that he never knew what was beyond the wall?
