Obliviot
A total mess who doesn't even realize they're the total mess.
"I didn't miss the bus. The bus just didn't want to take me.", while still standing outside the bus stop.
"I didn't forget my homework. It just... disappeared.", said the Obliviot who left it on the floor.
"I didn't lose my keys. They just went on a vacation.", while still looking for them under the couch.
