A best friend
I'm lucky when I have a good friend. The first letter of her name is "C". She is 30 years old. She is single now. She is working on accountant for a furniture business company. She is both garcious and kind-hearted. Almost people on her company like her. She joins every activities of company. Her company usuallly does charity for dead at cemetaries in over our country. She joins and goes everywhere. It's good but I worry for her. I think it will effect to her love. She cannot have a lover. With all she did, I hope she will be falling love with a good man. She's joyfull and friendly, she helps everyone with smile, she does without thinking and she works hard so that her boss appreciates her ability. I'm not good friend. I have just forgot her birthday. I want to have a apology to her. I want to invite her go to drink coffee and give her a gift.

Phổ thôngI'm pleased to correct your mistakes as follow:
1. She is working as* an accoutant
2. Almost people in* her company ( why dont use choose almost her colleagues like her. its ok :D)
3. I dont understand what this statement means. does charity for DEAD at cemetaries. Maybe I dont know what this event does.
4. I am worried about her. When you say " to worry someone" means to make someone worry.
5. It will affect her love. affect is verb, effect is noun. affect someone/something, no preposition followed.
6. With all She did, I hope there will be a good man coming to her/loving her. Fall in love with someone means you have special feeling with someone. But here I guess you meant A good man will come to her because She is a good one, right?
7. I want to send my apology to her.
8. I want to invite her to* go out and drink coffee/ invite her for a drink is more concise!
Good luck and keep going.
