If you look too perfect, the other party can't really find
anything to comment on and your converstions together will just go
dud. In another case, you look too perfect, the other party keeps
complimenting you, it just sounds like dud, coz you know you went
through all that just to make things really good. And so on the
next date, you have to make things equally good or even better,
otherwise it seems like you're just slacking off.
