blogging and steam

a friend called and saw my new blog,he whistled for some time then said ;i was trying to let off my steam,the way u try to let off yours through poetry,sketches and general writting;well he had his point and he was entitled to let off his steam but why in my room?that is precisely my point .he said ;what right do u have to let off ur steam in this way ,steam engines r a thing of past otherwise we could dock u in a railway yard;on this he remembered that he had to catch a train.he rushed out and train came to rescue my steam.
