Neighbours

Shortly after my trip to Winnipeg I got new neighbours next door: a small family with one young child. I went over and introduced myself, and they seemed quite friendly. For the most part they're pretty quiet. Frequently I can hear the kid running around inside. He seems quite active. However, frequently their "conversations" sound like shouting. I have no idea what they talk about... their voices are muffled, and they speak in Chinese. I hope I'm misreading their tone, and they're just "enthusiastic" speakers, rather than angry a lot.
