Astronomer: hey dude, Pluto is not a planet anymore...
Me: Pluto the dog was a planet?
Astronomer: Ha Ha, nice joke Gp, Pluto is reclasified into a Dwarf Planet
Me: So whats a Planet now?
Astronomer: Oh the usual suspects, the big guys, mercury, venus...etc
Me: Hemm...does it matter?
Astronomer: Why do you say so?
Me: There are probably a billion more things we dont know about the universe...
Astronomer: But there are a lot that we already know and..
Me: And never do anything about, so you go around messing things up?
Astronomer: We reclasified the rock, not blow it up
Me: Again, does it matter what you do? Its more of a cultural significance, people wont forget and forgive.
Astronomer: ahh...there are billions of more things out there to investigate and know, so does this matter....
