Congo comes out, and I handle him, at least twice a week. He enjoys it. In good weather he goes out on the lawn. In his tank he will often rear up for me to take him out, since he knows it's either an interesting outing, or dinner day.
He's a fine entertainer too. He doesn't mind if my friend's grandkids hold him. Though if there is a group of people and he has some freedom of movement, he will gravitate back to me. So a corn can recognize "their person", and can understand that he or she is the source of benefits
(Congo is a little mentally sharper in this respect than was my ex).
