We had two pigs. One was the sweetest, cuddliest thing this side of anywhere, and her sister was the complete opposite.
The sweet one would come up to you every time you entered the enclosure, and she'd stroke against your leg like a big kitten, while the other one would 'ram' you, or she'd chew on your boot, or stand in your way.
When you fed them, the sweet one would happily trot up to you, and wag her ...tail?, while the other would try to steal her food, always coming in from the left side (for some reason). The sweetie eventually got tired of this, and positioned herself one day, so her left side had juuuust not enough space for her sister to squeeze through to the food.
Let's just say, she gave a face to the term "squeal like a stung pig" that day. My ears rang for hours XP
They were both sweet in their own way though ^^
..... And no, I'm not talking about mini-pigs. I'm talking full-size.
