If you were to ask Peter how he got his black eye, this is what he would tell you:
Peter: Oh, well….Adam and me crashed, cause we were running in the night.
And he just got a bruise right there.
Peter: And….well, do you know what swollen is?
You: Yeah, I think I’ve heard of that.
Pete: Well, swollen means get bigger. And it got swollen. And it’s also called a shiner.
*I think we can say he has effectively learned all the terminology associated with having a black eye. He was confused by the “shiner” bit at first, but didn’t take long to adapt.
