when you knock, wait for someone to answer!

Our Mr. Landlord (who by all means is very nice normally) came around unannounced today to measure our french doors because they are basically crap and need replacing. I don't know whether he thinks of us as small children but he sure treats us like it. Firstly, Craig rings to tell him about the French doors and then Craig arranges a time for him to come round... Friday. Today is Thursday. He turns up, knowing that he can't get in to do anything but wanders around the back of the garden to measure the french doorsfrom the outside. Then he tells me that Craig had the keys so he couldn't do anything today. It breaches the contract when it says that the tennant should be able to enjoy the property, he is therefore trespassing surely. He is being so rude, and it's so belittling, he is patronising us and forcing us to think about the end of our tennancy. I tell you what sunny jim, we will leave when we want to, and even if you pushed the other couple out, you can't do the same for us. I am so mad angry. He then proceeded to knock on the windows rather than the front door, he should have just knocked, and then waited like any other sane person. I could have been ill and lying there in my pj's in a duvet for all he knew. He can't just come around and do this.
