Hey! Honestly, I AM a native English speaker... and I fumble up my words now and again! Particularly when I'm anxious, in a new situation and my mind is processing 100,000 things at a rapid speed! I've said some of the dumbest things! Particularly with similar sounding words!

It was OBVIOUS what you meant. If English is not your strong suit while speaking, it should have caused a pause, followed by understanding. It should not have ruined the day.
Her father's overreaction is more on him than you.
It'll be a funny memory one day, I promise. It's not a big deal!
