How do you get the person you deleted back on your buddy list on YoVille?

You have to find them on YoVille, either by starting an event saying "I'm looking for Luke" [or whatever his/her username is] and hope he/she comes or, you can search for him/her , and hope to get lucky but that's not likely. If you find him/her then click on them and click "Add to Buddy List" and hope he/she clicks agree.
