I got this dictionary right before I went to Mexico in the summer 1994. There was this boy I liked on that trip, but, you know, I didn't know if he liked me back. One afternoon I went to the corner to get a Coke with another boy on our team and the Mexican kids told me when I got back--"Mateo está celoso." I had to look it up.
"Matt is jealous"
It still makes me smile and blush a little.
