Manager’s bad behaviour

I always thought, that things I read about wrong project and personell management are enormously exaggerated. I was so wrong … Today I met such a guy, he is not really my direct superior, but he oversees a small project we are developing for his company. I attend regular meetings with him, and do some emails. However in every ( I mean EVERY ) email he asks “are you ready???” with the things we discussed. Not to mention that deadline is in 3 days. So I keep saying to him that everything will be made on time. That’s really frustrating. Fortunately he is not my direct superior, I would leave if he was 😀
