Misae's House
"Pardon my intrusion," Laura said as she walked into the house.
Misae giggled when she saw Laura acting polite. "Don't be so uptight. You're my friend and also Kanae's sister. Just treat this place as your home."
"Thank you, Sis Misae?"
Misae nearly choked. "Just call me Misae. You're not that polite at school."
"Well, that's because we're classmates at school," Laura scratched her head. It would feel rather awkward if she had to call every classmate using 'sister' or 'brother.' This was the reason she didn't use honorifics when addressing them.
It was indeed more polite to use them, and the cultures in several countries required them to do that.* However, there were also other places that didn't bother with them at all. All in all, it would depend on the place they lived in.
Misae shook her head. "Don't bother using an honorific. I'm not that strict and our ages don't differ by that much either."
