Although I've been fluently speaking Spanish for several years now, I do still make mistakes- and pretty funny ones!
The other day I saw a friend that I hadn't seen in a few days. The last time I had seen her she had been sick... so here's a little piece of our conversation:
Me: Hola Carol! Como estas?? (Hey Carol, how are you?)
Carol: Muy bien! (Good! Thanks!)
Me: Ah que dicha, ya te sientes mujer? (Oh that's great! So you're feeling like a woman?)
We looked at each other for a minute, as I realized what I had just said.
Me: Mejor, no mujer! Ya te sientes mejor? (I mean better! Not woman! Are you feeling better?)
We laughed and continued on with our conversation... but it's always funny when mistakes like these happen!
