Analisis kan yang kata mengandung past tense dikalimat ini Today is 16th August and tomorrow is my sister's birthday. Her name is Kristal. I want to give her a surprise. I have talked to some of her friends. They have helped me to prepare a surprising party. We have discussed it since July. We are going to celebrate my sister's birthday in a small restaurant near my house. Our parents have also agreed it. The restaurant has been booked by our parents. What about the birthday present? No worries, I have prepared it too. She loves art very much. I have made a painting for her. I hope she will like it. But I haven't wrapped the painting because it hasn't dried yet.
