I wouldn't say monitors are personal as a catch all statement. Some monitors and tegus for that matter have been known to display "affection", they are extremely intelligent animals, however there are 2 trains of thought on care, some people believe in the puppy dog tame giant lizard that will be on your lap for hours at a time is normal and that they are tamed down, others will argue it is because their living conditions are not optimal and if kept at the correct basking temps, the correct diet, etc that they will not be these tame lap lizards, but you will end up with a healthy, interactive, extremely intelligent lizard. Research is your friend, however you have to start digging, you will find quickly that if you search "care sheets" the information is dated and incorrect...
