(I did pic lol, it's so hard to write on my phone without typing!)
Random riddle that I think I made up but I really don't know whether it's actually a riddle already out there lol:

You walk into a house. There are 5 people in the house. You find the two parents in the kitchen and two children in the lounge. You then find that you need the toilet so you go upstairs. The light is on and the door is closed.
Do you open the door and go in or stay outside? Why?
