"Why".. What a Question..

Hmm.. What kinda question is "why".. Is it necessary that every "why" needs to have an answer??.. Sometimes.. try as hard as u might u cant the find the answer to a "why".. weird but u wouldnt want the answer to any other question but that "why"... If only we knew "why" on earth we want to answer a "why"?? (Recursive eh??..)
