The post icon should not mean that I'm unhappy, I'm only a bit thoughtful and as you said sentimental by thinking of many scenes; maybe a bit more happy icon would have been more suitable.

Some pictures above show these scenes what I mean; the first date at the lake(of course the second when Tad alias Stifler doesn't come I think we would have seen a bit more if he wouldn't have shown his videos to the other girls)

Well there are many scenes, descriving all of them isn't possible because it's the whole film that makes people talking about in here.
