And again a line from Totoro...
みんな 笑ってみな おっかないのは逃げちゃうから。
What is 笑ってみな? I tried googling if there is maybe a ~てみな form of the verb or something, but couldn't find anything... :/
Also, can it be that obaasan is talking in kansai dialect? There are so many words which don't exist in the dictionary... Thank you!
