The latin word, līmes, comes from many paths and hesitations, all the road, deep channelled river, Río Grande. A fortified frontier, rich in calcium and built for bones. A border line. Birdlime, meaning to catch anything flying north. Grandma sends me for limones, a variation on the word, line, meaning the umbilical cord connecting México to my backyard. I reach, pluck, pour into the té. I hand her the teacup, Grandma sips it warm, says it reminds her of home.
