I always loved seeing the llamas that were at the fair, and I was very happy when I got my first llama, a brown and white male named Gilligan. He had been handled since he was a baby, and was a very sociable llama. When he came up to me, he always put his nose right in my face to give me a kiss.
Llamas are very calm and gentle, and not spooky like a horse is, but they are also very shy and reserved; although they are extremely curious animals as well. They love to be led along and go for walks with you, and can even be trained to ride in a vehicle.
They are not strong enough for an adult, but can easily carry a smaller child. I used to take my granddaughter for rides up and down the driveway on Gilligan, and he seemed to enjoy it as much as she loved riding him. She was only about 7-8 at the time, so just the perfect size for him to carry.
Here is a great video of a llama that is trained to climb right in the car and go for rides with his owners.
