tired weekend

I joined my friend's birthday on Friday. He looks like my big brother and always helps me, when I am in a bad situation. He always says sorry or thanks to me and I don't know why he said it for me. So maybe he is very gentle with good manners. We celebrated until midnight. I continued taking part in friend's birthday's party on Saturday. We ate hot pot that is delicious in the evening. I made some new friends at the party. They are very cute, I like them, and then I spent all night watching movies until 9 o'clock the second day, so I had to sleep on the Sunday. I went to bed late on Sunday, so I was tired on the third day. I had to do my homework and prepare lessons. It was very terrible. What is more, I could not sleep until the second day at approximately 3 o'clock, so today , I am getting tired.
