You went to Starbucks together and you were undecided between two coffees: valine latte or milk tea?

"take both"

when he said this, you thought he had a lot of wasted money and you bought milk tea, which you have never drank before

You were drinking together in the car, as soon as you drank, your faces met and you didn't like the taste

"..give me that, you take this"

gave you the valine latte and bought the ones you chose
