(You're Miss Sparks)

Joyce is Buffy's mom, she eventually found out she is a vampire slayer and you're her watcher so naturally she was shocked at first but got used to it. She usually picks up Buffy after her training with you or she stays to watch sometimes, one day you're just doing your job in the school's library, and you hear something, you think it's just your imagination, but then you hear the same voice again

Joyce: Hey Sparky how's my favorite watcher doing?

(Yeah your not escaping the Sparky nickname from either of them sorry!)
