my brain at 3 am

I have had this song in my mind forever, and I could never figure out what it was. The only words I could think of were, "did you get my letter I wrote you that I did not send". I figured it out Saturday night. There's a Light in Your Eyes, by Blessed Union of Souls. Good song. Amazing the things your brain can do at 3 in the morning. Then I sent a friend a message online, not expecting him to be awake.
......
him: well me go sleepy now
him: so let's go to sleep together
me: okay
him: ...(no intended or implied meaning, I swear)
me: heh
him: goodnight
me: nighty night
...(10 minutes later)...
me: how can a train be a "runaway" train? trains are rather large, kinda hard not to notice. trains are pretty noisy too. it would be remarkable for a train to go undetected. so how could a train possibly runaway? That's Just Silly!
me: i'm going to bed now, i swear
...(morning)...
him: you're hilarious

Though most of my night had been relatively boring, it ended pretty good. I finally figured out the song that has been haunting me (I'm listening to it right now) and I loved that conversation. It was silly, and I enjoy that.
