Um...First please close your eyes.  Any light would interfere with looking at the stars. You feel like you're just going to fall asleep, then? Then please go home. No, I just don't want you to catch a cold.  No, you're not being a nascence...Sorry. Let's look at the stars.

Sorry that I was the only one looking. H-Here. Are you cold?  I'm sorry.  I don't have any extra heavy clothes.

 (SHOCK; EMBARRASSED)

Are you sure it's ok to talk to you?  I'm not annoying? You shouldn't spoil me. It was already enough that you  came today, but I might get too confident.  L-Like asking you to come see the stars with me again.  I'm sure you're busy.  This is troublesome, right?
