Just like no one wants to eat spoiled food, having to deal with spoiled people is no picnic in the park. And the following people know this concept all too well, as they recall the absolute worst case of a spoiled person they have ever seen.
"My toddler cousin, when I visited her while in college, apparently was treated to a birthday party whenever she wanted one. Complete with friends, presents, cake etc. She had had 3 or 4 that year already when I visited in the early fall... Yes, she didn't quite turn out 100% ok either" (Source).
