First in, first out.
A collection of dates for the time I was undocumented in the United States. While working in kitchens illegally, I came up accidentally with FIFO (First in, first out), a concept applied to the food industry. Cooks classify the food by dates they place in pieces of adhesive tape in the containers where it is packed. I started to collect the dates as a way of counting the days I had been undocumented in this country. As a reminder of the elapsed time.
