Moving Office

You are moving office. You would like to be behind Elisabeth. But Elisabeth wants to be behind you.

Is there a solution ?

I tried for some time and to me it seems answer is going to be no but I am not sure.

It's possible:

Place your desks back to back.


Move into one of Mobius' offices. Mind you, a simple looped office would work as well.


There is a virtual solution!

Seat Elisabeth and you opposite to each other (that means you face each other). Then have a full-size mirrors arranged at the back of each of you, such that the reflecting surfaces face each other and are parallel, which gives more than the number of seat arrangement required by you !! :-)


Yes if they are back to back..!!
