Flying home after a cruise to New Zealand/Australia, lunch was served. After lunch, I was looking around the cabin, munching some M&Ms. And what did I see across the aisle.... an older gentleman, had taken his dentures out, and was busily picking food debris out of the faux teeth. I was amazed. I nudged my wife and pointed out the drama across the aisle. She mumbled "goodness gracious" and decided looking out the window provided a better view. I said to her "is that it? We get so old, we don't give a damn anymore?" She withheld comment on my astute observation. I just started chuckling, then couldn't help laughing a bit. The wife kept giving me "death looks" imploring me to "cool it." Now, everytime I have lunch on a plane, I laugh thinking about it, and get an elbow from an unamused spouse.
As a bonus, we had an amazing cruise.
