Telling the Great Grandparents

So, Megan made these picture frames to give to her grandparents that said I Love My Great Grandparents. When they baby is born they can use these frames for his/her picture. We had them in for lunch, and gave them the frames as gifts. When they opened the gifts and read them, they read them as I Love My "Great" Grandparents, and not as "I Love My Great-Grandparents." It was super funny, but after a nudge in the right direction, they understood what we were trying to say...
