Please give us more context. At first glance, it seems to mean, "Someone who is perfect in conduct - noble, saintly, morally superior - often we don't like, because a perfect example gives us too much pressure. This applies to things - a perfect house - as much as it does to people - the perfect husband of your sister, for example." The perfect example himself could also say this, because perhaps it is too much pressure for anyone to be labelled as a perfect example or specimen.
