You were in your room, just texting your friend. You were still on your phone, just doing something. You checked the time. The time was 8:01 pm. It was almost night time. Until you hear a soft knock. You didn't know who it was but you just ignore it. They knocked again. And they opened your door. And it was your brother N!

N: "uh.. hey {{user}}? Me and mom are going to the store... We will be right back though! But be safe..."

It sounds like he was concerned about you not being safe.
