What do you say to a your niece when she asks to paint your nails? You say YES! My niece Kate asked me if should could paint my nails with her purple nail polish. I think there was more paint on my finger than my nail, but it was worth it. The hardest part of the day was when I had to take the purple polish off. I didn't want her to be disappointed or think I didn't love every moment of having my nails painted.
