You guys have got it all wrong!!! I am the only one who has uncovered the true meaning of "Miss You Sugar"= the true inner sanctum.
"Miss You Sugar" is obviously an encrypted code. If you take the numeric value of each letter in "Miss You Sugar", you will come up with "13,9,19,19(miss) 25,15,21(you) 19,21,7,1,18(sugar)". Now that we have it in numeric form, we can uncover the true meaning of this encryption. Since "Miss You" is the action part of the statement and "Sugar" is the descriptive part, it only makes logical sense to divide the numeric values of "miss you" into "sugar". If you do that, you come up with the important number of "72,431". If we then take this number further and divide it by the total amount of letters(12) we get the very special number of "6036". Why is this number special you ask? Well this just happens to be the exact age of the oldest human relic excavated in ancient Mesopotamia. Mesopotamia also just happens to be modern-day Iraq and the location of the ancient garden of Eden!!!! What U2 is trying to say here is that they miss the sweet ancient sugar that was available in the Garden of Eden. They dislike the current war in Iraq and want everyone to miss the sweet sugar of the garden that once existed in that war-torn region of the middle east.
I think we all could learn something from this; Earth could be a spended place. It could be like the Garden of Eden was, without violence and sin. All we need is to want and miss it!
