Dear... well, I don't know what to call you so I am just going to say "you." Dear You: I cannot believe I got on that plane. Just after the doors closed, I had almost decided to jump up, fake an illness, and back out. I was ready to do that when I felt the little thud that tells you the plane has started to back up from the gate.
Trapped. But the thud either caused or coincided with a tingle between my legs. The excitement of what I was about to do was talking to me. It was saying: "Hello. I am your excitement, and I'm coming with you on this trip. You didn't forget and leave me at home, like you may have thought."
Then I did what you said. I used that tingle against my panic. The fact that it worked - not completely, but it did work - gave me confidence that you knew what you were doing.
Which is weird because I was the one doing it. I was the one crossing my legs and bouncing my ankle to keep the current flowing as the plane sat on the runway. I was the one closing my eyes and squeezing pleasure from my helpless position in 22E. I was the one who called up from memory the dead calm in your voice when I phoned you earlier today and tried to back out the first time, before I caught the cab to the airport and got on this flight. I thought you would tell me, "You can't do that, you promised. We made plans!" It was a shock to hear you say, "Well, of course you can do that. You can change your mind. It's no good unless you choose it."
