Why certainly work is being done by the `blue' box on the `red' box and the `red' box on the `blue' box via the interactive forces (which must be equal and opposite in direction of course).
Good Luck,

You really want to say that?
How about this case: A guy on roller skates pushes off from a rigid wall. System = man. Any work done on the system? Does his internal energy change?
Further, in the real world, the guy will get a bit hotter if he does this several times. Any heat transferred to or from him (on short timescales)?
Howdy,
Do I really want to say the two forces must be equal and opposite? Isn't that Newton's 3rd Law?
I did NOT say the work done by the forces was the same.
