One night last summer, when friends were over for grilling, we busted out the supply of camping glowsticks and Otis went nuts in the yard. Bedtime came around and I took him upstairs to get ready. I was looking at my phone for a minute while I thought he was getting his PJs on, but when I looked up I noticed that his face had little glowing spots on it. I’m not entirely sure what happened (he might have bit off the end), but glow goop had splattered all over his face, hands, and the hallway wall. We got him cleaned up and then turned off the rest of the lights and took pictures of the pattern on the wall.
