Raining (Rain/Raining has only one N)

It's been raining for several days. I have a workmate she who leaves her umbrella in the company at work, so she gets wet when the next day morning, which makes her she is so upset. She says to us and tell us : (Use quotation marks like this " at the start and end of a quote, instead of :) "If you have an umbrella in on a rainning rainy day, how in happiness happy you are." (This sentence is composed a little strangely, maybe you would say "If you have an umbrella on a rainy day, it makes you happy) and Then she complains to us "People who have umbrellas around me,they don't have a warm hearts. They watching me getting wet in the rain, but they don't share their umbrellas to with me. I am  It makes me so sad." 
I don't think so that's true. They don't know where you want to go, and or if you need help or not, so we you couldn't can't blame them. If you ask to them: "Can we share your umbrella?", I think most people would be glad to do this, especially with a beauty.

Very good. I easily understood you. I will give you three suggestions. First, when you are quoting someone (Saying exactly what they said) use quotation marks " " . Second, when using commas, use them like this, with the space after the comma, instead of like this ,with the space before the comma. Lastly, try to make sure one sentence doesn't go for too long. But good work.

Raining

It's been raining for several days. I have a workmate who leaves her umbrella in the company. She gets wet when the next day arrives and she is so upset. So she tell us, " If you have an umbrella on a rainy day, (this part doesnt make sense). Then she complained to us and said, " People who have umbrellas around me, they do not have a warm heart. They watch me get all wet in the rain, but they don't even share their umbrella with me. I am so sad." But we wouldn't know unless you asked them. So we cant blame them. If you asked them, " Would you mind if we share the same umbrella please?" Then I think most people would be glad to. Especially to a beauty.

Instead of using the colon (:) to open the speech use what I call speech marks (") to open and close the speech. Other than that if you re-read your paragraph, you'll notice that you could easily correct the mistakes that I have corrected. That was a beautiful story though :) Good job!
