and the French think I speak French comme une vache espagnol (like a Spanish cow)!

They call you a cow! (kinda). Those rude French people.
Did you learn some Spanish before you learned French? Seems the first "foreign" language we learn influences any others we try to learn. I learned a little French before I went to France on business. We had French liaisons at the plant. I said to one of them "Je ne parle pas bien Français".
He said "Yes, but you don't do it very well".
I said "I know!"
He said "No, I mean you did very well saying that"
