Do you want some watermelon?

He used both Korean and English is a sentence so my brain tried to use both Korean and English…

네 is yes in Korean (though it has more meaning that just ‘yes’ in English but let’s not go into that) and sounds something like “neh”. So that’s what happens when you combine it with ‘yes’….

Some days I feel like my English is deteriorating but my Korean is not getting any better.
