This e-mail is for when you want to ask someone out, but are too nervous to do it in person.
Okay, so I don't have the guts to do this in person, all right? But at least I'm not passing you a note in class. The thing is, would you like to go out? With me? Just us? Either you're smiling (a good reaction), or laughing hysterically (not so good) or screaming "How dare you!" at your computer (definitely bad). Whatever the reaction, I hope you'll at least reply. If you want to go out, I guarantee I'll show you a good time. I was thinking about going to <location and time of date>. I await your response with a bag over my head (to prevent hyperventilation) and a beating heart.
