Whom to invite??

We're supposed to have 120 guests only but we have to allot extra for our suppliers and "uninvited guests". Yes, that's right. I was told that eventhough we're going to be really strict with the number of guests who will be coming on our wedding, we can't have control over unexpected guests so we decided on having a total of 150 guests. I thought listing down the name of the guests we're inviting would be easy but it wasn't. Then one day, I found this pic on one of the blogs I came to visit. Thought it will be a big help to me since I'm really having a hard time choosing my guests. lol

So for those who are like me, hope you find this one helpful too!
