I was watching the news -> link and I believe the narrator said
The first translation that pops up in my mind is "really childlish" or "immature".
However, I'm not sure if this is what the narrator really meant??? For me, it's a pretty harsh word to describe a person, especially the one you aren't close with.
Hence I was wondering what did the narrator actually want to imply in this video? and Is there a better English translation that are more align to what she really meant?
or is it that these words just are not as harsh for Japanese?
