Nosy neighbour

I can't help thinking myself as a very nosy neighbour who is quite annoying. My neighbour left for Italy few days ago, the teenage kids at home are under the care of their college-going eldest daughter. So my neighbour told us to keep an eye on them. I couldn't fall asleep one of those nights after soothing Cheng. I turned on my phone to find that the schools closed the following day due to the haze. Then, I heard the car's engine noise outside. Thinking it was the school bus that came to pick the boy, I thought I should be a caring and loving neighbour to alert them about the government's instruction, but I saw the girl get into the car and off they went. This happened at 4 sthg in the morning. About one or two hours later, they came back. The youngsters nowadays have a lot of catching-up sessions with their peers at the wee hours. Last night, hubby said they partied until midnight while I was sleeping like a log. However much I talk about them, I do not have to worry though, they have CCTV at home, the parents should know what the kids are up to. Probably they did not party but video-calling the parents abroad, who knows?
