Dear Jack,̶h̶̶e̶̶y̶ ̶j̶̶a̶̶c̶̶k̶ how are you?I have to tell you something . Yesterday we bought a new house with a big garden! The house has two bedrooms , three bathrooms , and one kitchen. It´s great! It´'̶s̶ cost 100.000 pounds. Our dog has a wonderful doghouse in the garden . it`s pink and blue but j̶̶u̶̶s̶̶t̶ my sister Jackie didn´t like it . I said she is mad , because the house is wonderful. But now our family fund is empty. My dad says that´s okey because the house is great. o̶̶h̶ now ̶c̶̶o̶̶m̶̶e̶̶s̶ the surprise - in our garden is a very big swimming pool! It´s in the middle of the garden and it´s very big , about 30m²! But ju̶̶s̶̶t̶ my sister didn´t like the swimming pool. I didn´t know why , because she is a teenager and she can make̶s̶ poolpartys. I hope my sister change her opinion. Oh and our bathrooms are very big! Yes you heard right we have two bathrooms. In both bathrooms are two toilets. Okey that was it from me .
See you, Emely
