I've dealt with some humans in my time, and your interactions with them will be shaped by several things:
1. Size: Perhaps the most obvious. Judging by what you've said, it appears you are about 6 times the size of a human, which should remain comprehensible to most, if a bit unnerving. At about twelve times their size, most humans lose their sense of scale and can only determine that you're "really really big". This frightens them.
2. Technology level: Humans actually have various subgroups with varying levels of technological proficiency (which may be hampered by the size difference). Some humans can actually use a miniaturized version of universenet.
3. The human's culture and personal preferences and beliefs:
Every human is different. Some humans still cling to a monotheistic religion that denounces the existance of anything mightier than themselves, claiming all such entities (with one special set of unattainable exceptions) are evil and must be obliterated. Contrary to what some say, humans DO have a sense of right and wrong, but it varies by individual, and captivity often forces them (from their point of view) to take extreme measures.
There are a few subgroups in particular you'll want to watch out for. One group grows their head-fur long and wears black garments with white trim; some of these are violently opposed to any technology electricity-level or above. Another bunch of subgroups seek to control their fellows using fear; they have a reputation for going down fighting (sometimes blowing themselves up), so unless you're catching your own from the wild, you probably won't have to worry about them.
Some humans need different levels of activity. Attention spans can vary. It should be noted that a human without companionship will gradually go insane, so if you're going on a long trip, make sure your human has someone else (whether another human or a pet caretaker, perhaps a friend or relative) to interact with regularly.
Some humans will go into captivity shock; being in the midst of things so much more massive and complicated tends to scare them, and they'll rarely leave their shelters. Some just roll with the punches, adapting as needed, and a rare few are extremely inquisitive, to the point that they can learn basic communication methods with your species (though if the size difference is too great, your voices might be out of each others' hearing ranges). The inquisitive types require the most maintenance but are (in my opinion) the most rewarding; I've heard rumors of a fellow who trained his pet human to assist him in small-scale technology repairs.
