First, the girl & her daddy:
TB (the boy), delaying bedtime: Don't turn off the lights! I'm afraid of the dark!
Me: Since when? Why are you scared of the dark?
TB: There are ghosts.
Me: Mean ghosts or nice ghosts?
TB: Most are nice, but some are mean.
Me: Tell them to go away.
TB: Sometimes they won't.
Me: Should we spray water at them?
TB: Mom! It'd go right through them (i.e., don't you know ANYTHING?)
Me: Should we turn on the fan so they blow away?
TB: No, the only thing that works is vacuuming them up.
Me: Oh - those aren't ghosts honey, those are dust bunnies.
