My niece is obsessive compulsive among other problems. She found this poster laying around that had the first 151 Pokemon listed with their names next to them. She had just learned how to read and write that year. She decided that she was going to write out all the 151 Pokemon's names on paper.
But she ended up just writing "Bulbasaur" about 100 times. She couldn't stop writing the first Pokemons name.
I always wonder if she knows shes doing it and just can't stop or...
