"I wanna see Heaven"

The other day, my dad was showing Jack some pictures of Papaw, my grandfather, who passed away about two years ago. He told Jack, "Papaw is in Heaven." Riley, sitting close by, knew that they were looking at pictures and overheard the comment and, thinking that those were pictures of Papaw IN Heaven, exclaimed "I wanna see Heaven" while straining to catch a glimpse of the picture.
