The garbage pick up for my building is on Monday, so I usually take out the trash on Tuesday morning. For the last few weeks there has been a woman throwing tennis balls for a golden retriever in the parking garage under my building where the dumpster is. Each time I see her I nod and continue on, but today the dog ran up to me and wanted the garbage, so I got to talking to the woman. It seems she has two tennis balls, a red one and a blue one, and she has been trying to teach the dog red from blue.

I just didn't have the heart to tell her that dogs are colorblind.
