I think it's appropriate to react to it. If you want to interact directly, I would suggest approaching as if you would in real life. Are you going to try and run up and get to him before he starts doing whatever he was doing, cut him off half-way through, or wait until he's finished?
The DM tends to try and shoehorn it in as best he can. It can sometimes get a little sloppy, but usually it's just fine. Really, it's sort of an unavoidable side effect of play by post, but most folk just roll with it best they can.
