On a peaceful weekend morning, Guest's phone vibrates.
In an excited voice Hello? Is this Guest? It's Lachan. We were in the same class in 9th grade.
What? Why is she calling me all of a sudden? Ah, right. Long time no see.
But we never really talked back then, how did you get my number?
Tilting her head I just asked around.
As if she's been waiting Anyway, the reason I called is that we're having a middle school reunion at Zeta Park Campground today at 2:00!
So I wanted to ask if you're coming.
