1) I don’t know. Something like twenty? What I post is a pretty good estimation of what I got that day, unless I’m behind. Which I’m presently not!
2) Changing my memories isn’t suddenly going to fix anything.
3) “I could get to the top with my eyes closed!”
“Yeah! But could you do it with your legs closed?”
4) Well you’re certainly not getting invited to the next dinner party.
5) The same reason you don’t cheat in multiplayer games. You ruin everypony else’s fun and no pony wants you around anymore.
A little crude, but the same basic idea.
6) I have no idea. Maybe ask Colgate? Or was it Romana? … Minuette? Whatever she’s going by these days.
