Just some minor points I'd like to add--if you try to pet a nearby bunny and they start hopping away, don't keep trying to pet them. I've found that it usually makes buns scared, like they feel as though they can't get away. If you let them leave without making them feel chased, they're going to be more comfortable approaching you. Additionally, make sure you always approach/reach for them from the side. Their eyes are on the side of their head, so if you're coming at them from the front they may not be able to tell who you are and mistake you for a predator.
I'd also like to suggest telling them if you're doing something important (to them), especially if it's an action you have to do often. For instance, if I need to pick my rabbits up for any reason, I always say "(bunny's name), I have to pick you up!" I made the mistake of never telling my rabbits when I was going to pick them up, and accidentally ended up conditioning them to be afraid of me standing and approaching them (this was during a time a frequent vet visits), because they never knew if I was going to grab them or pet them. While the trade off is 'they know when I'm going to pick them up and will run away if possible,' I personally think it's worth gaining their trust in this way. My boys know several phrases; the ones I get the most mileage out of are the aforementioned "I have to pick you up!", "no nibbles, no digging!", and "can I pet you?" Obviously, it's up to you if you decide to go this route; I can understand why someone wouldn't want to do this.
If you ever have to discipline them for any reason, NEVER attempt to do so physically. This will teach them that humans (especially hands) = bad. Keep a spray bottle nearby, set to
mist (not spray!) for any mischief. I will warn the rabbit in question usually three or so times (the "no nibbles, no digging!" phrase) before spraying them, so they know what that phrase means. Nowadays I don't even have to keep the bottle nearby, usually just warning them is enough to get them to stop.
If you're like me and are terrible at coming up with things to talk to them about, I'd like to suggest reading a book aloud
