If there's one type you don't want to hate you, it's ghosts. I mean...you don't want any pokemon to hate you but ghosts can and will make your life hell.

[Seriously, have you read some of those pokedex entries...]

Anyway, that kinda sounds kind of like a baby thing to me. I have had a few that were overly enthusiastic and energetic when they were younger but mellowed out as they got older and evolved. [A beat.] And then I have two who didn't. And one of them is a nine foot ghost-rock so you can imagine what that's like sometimes. Hopefully you will get lucky in that regard.
