Good morning Bryan,

Thank you for your letter again. I also like the korean actress 전지현 because she is very pretty and I like her in her drama My love from the star. 별에서 온 그대

I hope to see her in person.. ^_^

Well, as I noticed, your common mistake is the capitalization of letters. Please remember that if you are going to write a sentence it shoud begin with a capital letter. For example, "It is a typical hollywood drama film." Also, the proper nouns such as name of a person and name of the place should begin in capital letter as well. Example, Seoul and Paula. Just be more careful. Have a nice day. :)
