Genesis 8 -11

Sorry for not posting in week 2. I've found it really difficult to understand last week readings in the OT, because 1) my knowledge about the Bible is extremely poor, and 2) I'm confused with the people, the place and the events written in the Bible..

Some thoughts on today's Genesis:

8:15
Noah was obedience - He left the boat only when God asked him to do so, even thought he knew the water was gone.

9: 20 - 27
Ham saw Noah was drunk and naked, and Canaan, son of Ham, was cursed.
It doesnt really make sense to me as I think that Noah was the one who did something wrong; 1) he was drunk, and 2) he was naked. But why was Ham's son cursed? Shouldn't Noah be the one who should be punished?
And it also reminds me that even as obedient and righteous as Noah, there are chances for us to make wrong decisions and the consequences of that decision could be quite influential. It does not only affects yourselves, but also the people around you.
