I have a story
Sometimes when Im speaking in english, I just translate my spanish thoughts into english and say them outloud.
I was at a friend's dorm and there were like four more people there. Everyone went outside to smoke and my friend forgot the dorm's key. We had ordered a pizza and the pizza guy came and since we were locked out we didnt have money to pay, so we started asking random people that were in the street. Two guys that were drunk went by and we started calling them, when they came I asked one for money and started begging him for five dollars. The guy kept saying no, and I said "I will get on my knees for five dollars."
What I had said seemed perfectly normal in spanish, but after I said it outloud in english I realized that I just had offered that guy head. The guy started saying nasty things that I cant remember, and I turned all red. Always happens to me
