Our big guys (and gals) all have an abundance of "personality". I won't delude myself by saying they "love" me or they crave affection like a dog or cat will, but many tolerate or even seek out interaction with people.
Retics will run the gamut just like any other species; some will be chill, some flighty, some nippy or defensive, etc. We purposefully avoided buying any female babies that didn't tolerate handling right out of the egg, and our two mainland males are adults who were known to be chill even during breeding - some males can become difficult when they mature.
That's not to say we're not careful with them, or that they won't change in the future, or we take stupid chances during handling sessions - a bite from an adult retic is gonna hurt! As newcomers to bigger snakes we knew we lacked the experience needed to keep a difficult animal though, so our purchases were driven first by temperment and then by morph.
