As a coffee lover, when I say :"The coffee's getting cold."
Means: why you change this quick?/something wrong or weird about you.."My mug is broken."
Means: Sorry, I don't want to talk about something right now."Would you mind if I share this coffee with you?."
Means: Let's talk/ I want to share something/ I miss talking with you."It's bitter but good." Means: I can endure it don't worry."
"Coffee?" Means: Relax for a moment.
