Good mourning Tara~ I'm sorry about the unexpected absence of today's class. I was upset this mourning because I knew that I leave my jacket to our restaurant. My wallet was inside of the jacket. So, I had to go there to prevent to lost my wallet forever. Fortunately, Anyone didn't take away it. So I'm happy to day to get back it. Anyway. I beg your pardon about the unexpected event again. Have a nice day teacher. See you next tomorrow Bye~
