Although I did not have a plan, I did luck out in finding some me time. The one thing that helped me initially is my enjoyment or running, since it is really hard for people to argue against a person staying in good shape. But running isn't all that much fun, and I couldn't go for any epic runs and feel like crap the rest of the day; otherwise, there would be problems.
Where I really lucked out was a delayed flight. Suddenly, plans to pick up multiple people meant that we would need separate trips for the people. That means I had to drive an hour to the airport to pick up a family member. This was basically the best news ever. I got an hour in a car by myself. Also, I can get there early, frame it as me being responsible, and literally just sit there, listening to the Art of Wrestling podcast. It was glorious. Plus, it gave me a reason to go out of my way to get myself a lunch that I could not normally get which added an extra bit of awesome to my day. Also, the drive back gave me some one-on-one time with my airport guest, and I can say that all of my airport guests were great conversationalists. I ended up making three trips on three different days, and it was the greatest thing that could have happened to me. I have a feeling of euphoria just looking back on it. Ah, memories.
So, grooms, even if you aren't big on fitness, volunteer for airport duty. If you’re a stupid oaf like me, you usually just get in the way of things, so it should be easy for you to convince the bride that it is a great way to stay out of the way and still be productive. Best of both worlds.
