I'm practising my English writing skills: My cousin is so cute ^^

I had some great days with my cousin. Her parents had a business trip and this gave us time for our to do anything we want: Playing games, Hanging out for and eating junk food ..etc.. Of course that is those are all things which her parents rarely permit she do it her to do.We were free!.
She painted a person’s face by with some trees and a few of fish as well,. She also likes painting so that’s many abstract paintings are hanging up in her room, besides she’s quiet a mathematician and she speaks English very fluently although she has not learned to present perfectly yet!. She just is in sixth grade grade sixth,. I’m so proud of her.
I remember when we had an English article and she chooses chose the topic “Gossip Girl” to read, This topic make made her curious about teenagers ^.^, We translated some vocabulary words and I will never forget her emotion when she read to the sentences : “Serena had sex with Blair’s boyfriend..” Suddenly she yelled loudly “ OMG I’m still young!! I’m still young !! I won’t read this article anymore!” Haha I couldn’t stop laughing because my cousin is so cute ^__< .
But you know she is really concerned about Zodiac so let tell her your birth she’ll tell you that what Zodiac sign do you belong to?. 
Now I am missing her a lot!.

Very good, Mai. When you use exclamation mark (!) then you do not need a full stop (.)
