Riddle

[Austin]

Here's a little riddle, Whoooo can solve it.

You are in a house on the first floor, with 3 light switches. On the floor above you there are 3 lights. You can only go upstairs one time and back down. How do you find out which light switch goes to what light on the floor above you.

you cannot go outside and look through the window, cannot go half way up the stairs and see any of the lights. Cannot peak your head up the stairway and be able to see any of the lights.

goood luck
