What is the most heroic thing you’ve ever done?

I’d like to say, last night was a non-heroic thing since I could sell my friend’s DVD player for only Rp100.000 to a stranger from the original price, which was about Rp300.000. Just because he didn’t have financially secure plan for the next day in addition of his pregnant wife, and still have no idea what to make them feel save after Rp100.000 ends.
