Tom: Hey Sarah, are you free this Saturday? We’re planning a small get-together at my place in the evening.
Sarah: Hi Tom! Yes, I’d love to join. What time should I come over?
Tom: That’s great! Come around 7 PM. We’ll have some games and dinner.
Sarah: Sounds like a lot of fun! Should I bring anything?
Tom: Just bring yourself and maybe your favorite board game if you’d like. Looking forward to seeing you!
Sarah: Perfect, I’ll bring Monopoly. See you on Saturday, Tom!
Tom: See you, Sarah!
