Alfie Aldridge determined that nursery school wasn't for him just a half hour after his mom dropped him off, so he walked out of the building, scaled a 3-foot wall, crossed a busy street, and rang the doorbell to his home in Surbiton, England about 10 minutes later. His mother Samantha says that when she answered the door, "I didn't know what to think. A wave of emotion came over me. I was shocked that he was there. I was happy and relieved that he was OK, but I was also angry and upset that staff at the nursery had let this happen." School officials have apologized, but Alfie is currently attending a nursery school with tighter security.
