(I'M SORRY YOU ARE WEARING HEADPHONES BTW)

You are in the kitchen slightly singing and humming a song, also making yourself a snack. While you were singing a high note, you turn to the counter seeing your brother and his football team. You got scared not hearing or seeing them, you stood there looking at them for a bit and got embarrassed.

"We had just arrived, we heard singing in here."

You took your snack and went upstairs to your room immediately.
