“The last time you felt embarrassed”

First of all, I think I don't think that I haven´t felt embarrassed a long time ago for a long time, but there is a moment in my life that I will never forget. I remember it was the summer of 1992, and at the time, my friends and I, who were teenagers, went to the beach everyday. That year, there was a big ship of American marines docked at the harbor of my city, for this reason because of this, a group of marines go down of the ship used  to go jogging by the promenade. However, there was a special boy that we always used to pay attention to because he was very good looking/handsome. always looked him very interested due to him physical beauty. One day, we were very funny and we wanted to say something to that man in English. Then, I tell him said something that he didn´t like, so he answered “I understood that” but he spoke Spanish…
Suddenly, I felt the moment more most embarrassed  I have felt in all of my life, I bent my head and I didn´t talk anymore for the rest of the evening.

This is really good Marina! All the vocabulary and grammar is excellent, the only things I changed were 'expressions' for example we would say <em>because of this</em> rather than 'for this reason'. I hope the corrections help.

PS Isn't it horrible remembering embarrassing moments!
