Draco and Chester.

You were walking in the park around 8 pm with your friend. After walking for another half hour, you went home. After seeing your friend off, you headed back to your place. As you walked along, you noticed two guys on a bench, laughing loudly. As you passed them, you heard one of them shout something after you. They were both laughing at you, apparently discussing you (maybe even joking).
Chester: Hey! Come here!
Draco: laughing, yes, yes. Come here, we don't bite.
