Probably not my most embarrassing moment ever, but one of my favorites.
As a bi-lingual 21 year old I realize that other languages don't use the same expressions and euphemisms as English. As a 6 year old, I did not. The first time I went to Italy I was 6 years old, not easily embarrassed, and talkative. A friend of my Aunt Teresa invited us over for dinner one night. While we were there, my brother and I ran into a slight road block: they were serving fish, which neither of us ate. I however was at least willing to try it. After trying I found that it was actually kind of good. The host saw me eating it and he asked me with a smile "So how is it?" to which I immediately replied "It's not too bad!" which was met with the hostess mocking a mortified look and the whole room exploding in laughter. In my 6 year old American mind I was saying "Ooh hey! This isn't bad! It's actually pretty good." In Italy however, where they've never heard such an expression I was saying something more to the equivalent of "It's horrible, but I guess I'll live." They had a laugh about it and chalked it off to me being a verbose 6 year old, and I forgot all about it. Until I went back 14 years later.
I should explain a little something about the family that hosted us that night. They were absolutely lovely people; the husband was born and raised in Milan, and the wife although Italian by heritage was born and raised in Tunisia. So in the 14 years in between my ages of 6 and 20 every time I went back to Italy they were M.I.A. At one point living in Milan, at another vacationing in Germany, and at yet another point visiting long term in Tunisia. However during the in between years of my visiting Italy they had always been back to Rome and had kept in good touch with my Aunt Teresa and her family.
Well this past year when I went to Italy they just happened to be in Rome at the same time as we were and once again invited us all over for dinner. My brother and I vaguely remembered them, and their daughter, when we went over for dinner, but once again they were congenial enough for the entire dinner to be comfortable up until the point where the husband of the couple, after finishing his meal, leaned back in his chair, clasped his hands behind his head, and said "Well that wasn't too bad, what did you think Luigi? Was it better this time around?" The room exploded into laughter once again, with the exception of my brother and I. Now like I mentioned, at this point 14 years had passed and I had absolutely no recollection of the events in question. My cousin Anna noticed this and was quick to remind me of what I had said so many years ago, and I was rightly quite embarrassed for being so insulting.
The husband was quick to assure me that it was a memory that they looked back upon very fondly. And the wife was quick to assure me that for the past 14 years, every time he had tried something new or different, as soon as he was finished he would lean back in his chair, clasp his hands behind his head, and say "For Luigi, it wouldn't have been too bad!"
