Fucking Mesprit

Last time I play Pokemon Diamond before bed.I've reached the part where you have to catch Mesprit and it's super irritating. In my dream I was actually chasing something and I had to catch it. Then I got to a gym, one of the courts here at Mary Washington, and I got it to stand still by using mean look on it. Then 7 other people came in to try at catch mesprit, but it evolved into something like a dragonite, which meant a massive HP boost and no moves could hurt it at all. So we all started throwing pokeballs at it until eventually we gave up. And the dragonite was like HAHA you can't catch me and it "fled"
