Do you ever use yours as a tool? I remember the first time I ever thought of a strictly utilitarian image. I was at a doctor's clinic and needed a quick way to jot down office hours. Being without a pen and paper, I just took a photo of the sign. Now, of course, I often use my phone camera rather than making notes.
In today's case, we were in the Playa del Carmen Walmart. Most of the vegetables needed no translation. However, I knew that I needed to look these up when I had an extra moment.
I still am not sure if these are primarily for birds or people.
