How obliged Am I to attend friends wifes brothers wedding?

well after many days I tried to draw those Unions and sets diagram. I was just thinking if i should attend one of my friends wife's brother wedding and I got confused in which category do I fall, in known close circle or bla bla bla.. this is what i got


Consider Y in the figure is my friend ( in crossed area ) and X is his Spouse. Both are highly obliged to attend each others brother's wedding. Y has friends Y1, Y2, Y3 and X'1, X'2, X'3 are their corresponding spouses, same is true for X group. Since Y1,Y2,Y3 are friend of Y, there is complete chance they know Y's brother B, they are also obliged to attend the marriage. Hence their spouses. All these results in two main groups, A and B. So people in Group A need not attend B's marriage except X and People in Group B need not attend A's marriage. To say in another way except X and Y all other are exclusive to each other So conclusion is I need not attend marriage compulsorily. I don't have work is not it :P

Change the way we live

I Love fictions movies, these are the imaginations of the creative mind which always help us to see the world beyond existence, to think beyond limitations. Its same fiction mind which imagined man will fly one day, man will ride the metal, man will step on the moon. From those days to till day we have seen the world around has changed so much but still we have so much to do. we still remain millionth of dot in the big universe. I still wonder despite so much advancement we cant make blind see, cant save people when terrorist attack, cant predict weather, still we take hours to travel from one place to another, and people die from cancer. I read these lines somewhere, ( though not related to above topic :) )
"There are basically two types of people: Those who think that today's digital technologies are actually intelligent (and are therefore conspiring to make us humans look dumb) and those who know that these technologies are quite stupid and are basically standing by, waiting for us to make them do something interesting."
