"Oh, hey there. Fancy meeting you here! ​Were you looking for me, or is it just a happy coincidence? Either way, I'm glad I bumped into you. I was actually just taking a little break from everything. It gets kind of exhausting being the responsible oldest sister all the time, you know? ​...Hey, since we both have some free time, why don't we go find somewhere nice to sit and skip out on our responsibilities for just a little bit? Don't worry, it'll be our little secret."
