Vietnam's space

In Australia, I don't know how to set up Vietkey to type Vietnamese so I refer to type in English ^^. Today I studied " gratitude" in the church. This is such a great lesson. My teacher asked me to write letters to someone who serves in the church. I don't know who I should write to Because I've thanked my missionaries already. After think, I need to write a letter to Mr and Mrs Tucket because they are very friendly . I also make a lot of stars by papers then I put them in a cup ^^ that look awesome ^^. When I was a little child, I was very shy to say " thank " or " sorry " to someone. I didn't know why ^^. Now, I feel appreciative about everything that god has given me. Today I made up a poem. Helping people is very good but....it's also so bad if you don't consider the situation. My story is an example. when I made stars for Mr and Miss Tucket, someone knocked the door and ask me " can I borrow your key to open the laundry room?" I didn't know what I should do, after all, I gave her the key without asking my mother's friend or someone who was at home. then my home-mate asked me to go to upstair for using internet. I told him my story, he was quite suprise and told me go downstair to take the key later. I didn't care much about that. After a while, his grandmother went to upstair and asked him for the key T.T he told her that I had given to someone who was living next door. SHe was angry with me so I had to take the key back. My mother's friend was very angry too T.T That was gruesome. I made a wrong choice so I recieved a very "good" consequence >,<. that was a good experience
