Sorry, but what are you supposed to do? Turn the light on next door, or find out which switch it is?
If you just want to turn the light on, you flick each switch once then check. If it's off, flick each switch once more.
If you need to know which switch though, I have no idea
What's up with this glass? Excuse me? Excuse me? This is my glass? I don't think so. My glass was full! And it was a bigger glass!
