I'm currently a physical therapy student (not for much longer though!) and I recently traveled to Guatemala for a service trip. When we weren't treating patients, my classmates and I were lucky enough to explore some of Guatemala and learn about their rich culture. One day, we toured a coffee plantation and learned this fabulous toast:
Deseo que su café sea negro como noche, fuerte como la pasión, el dulce como amor, y caliente como infierno.
Translation: May your coffee always be black as night, strong as passion, sweet as love, and hot as hell!
