based on when I jokily asked my mom if I could get a pet rat, and she replied sarcastically "Yes, get a rat and name him Seonghwa"
Well... if I had a rat, I wouldn't name it Seonghwa.
I don't know if Seonghwa would be offended if someone named a rat after him.
I don't think I personally would be offended by having a rat being named by me.
And well... naming a rat Goose sounds a bit ironic.
