What's really fun, while learning, is making mistakes while practicing with strangers. My most crushing and embarrassing mistake was when I tried to say I was hot while making small talk with a waitress. I said "soy caliente" instead of "tengo calor". I immediately knew I made a bad mistake when she gasped and practically ran away. "Thankfully", a guy at the next table heard, (which of course means others heard my goof) He saw that I was a foreigner who butchered his language and he was kind enough to explain what I did. Instead of saying I was hot, it came out as "I'm horny". Yes, that's what I wound up saying to a woman I didn't know and of course many people heard. This scene would have been perfect for one of those Southwest Airline commercials where they say "want to get away?" I wanted to die right there but the people were such good sports about it. I've made many other bonehead mistakes but this one was the most embarrassing.
