I've had very similar issues in my mid teens when learning Spanish and visiting with my grandpa (abuelo). The kids on the beach I played football with seemed surprised that I had come to Spain with my "albondigas" and my urgency to get back to the hotel in case those albondigas was wondering where I was.I had a linguistic mix up in Porto. I don't think I'll return there.
At the time I was trying to learn Spanish, and for some reason after reading obrigado as thank you in Portuguese I kept saying ALBONDIGAS. Of course, that means meatballs in Spanish, so, me saying it repeatedly in restaurants every time a waiter or waitress brought me water or wine or food must have had them think of me as Mr Meatballs or The Meatball Man. To the waiting staff of Porto I could only say meatballs. I remember loudly shouting it as we left one establishment.
I asked my girlfriend on the evening of day 2, as the truth of the embarrassment that enveloped or every move there came to, why she hadn't let on, and she said she didn't want me to feel bad. I presume she thought it would come to me quicker. But meatballs obviously can't meatball that meatbally. Meatballs.
