Could somebody check my writing?:D

Hi Paul, I’m sorry I haven’t written to you for a month but I was busy studying for my exam. I am very delighted that you are going to spend year in Poland. It was difficult to believe that we meet again after last holidays. I suppose it will be amazing time when you arrived. I have to tell you something. In Poland we have different weather than in Australia. Sometimes, especially in winter there are subzero temperatures and you have to be equipped with warm clothes. In the spring we have a rainy season and very often we are escaping from a thunderstorm. Last summer I was going to my friend. The weather was very beauty but suddenly I saw an enormous sandstorm. I stared running and I hid in the cellar. After three hours everything was finished and I could go to my friend and tell him about it. You should take with you some warm shoes and a lot of sweaters but in my opinion you ought to take with you money since we have everything in shops and it will be easier if you buy most here. That’s all for now. I hope to hear from you soon. XYZ
