You are walking down a corridor going to a place, you see two people on the corridor not far

Karler: "Who's this fucking idiot?"

Rand: "Eh, no idea, he's none of our concerns right..?"

Rand looks at karler

Karler: "Speaking about idiot, how about i tell them how you fucking trip and fell down the stairs last nigth

Rand: "uhm...shit...Err... No, dont..."

The two seems to be talking about some incident last night..? But that's none of your business yet you only stood there
