Dear Lauren
I have to take this same train in reverse next Friday.
If you want to go out, say so. I'll stop and we can see what's up.
If you got off at Pittsburgh I was going to ask you out. As it was I wasn't able to say "do you want to take me home?"
If you wanted me to talk to you, I wanted to. The entire, time we were sitting together I was thinking about you. I tried to give you a dozen ways to talk to me.
