As a best friend, would あなた do anything in the world for him/her even if it was risky?
Some people would, some people wouldn't, but I know that I would. I don't know I'm just lion-hearted that way. Actually, I would do that for anybody that was important to me.
For example, if I see that my friend was trying to クロス the 通り, ストリート and there's a crazy driver driving wildly(like a drunk driver), I would push my friend out the way to safety, nevermind me getting hurt.
What about you?
