It's raining in Florida.

Today, the day began cloudy and a lot of rain fell.  
I am very tired of this weather. I was born in a place where it is very cold in the winter. Now, I live in Florida - a beautiful state with a lot of beaches. I have been living here for 7 months, but I was hoping that the weather wouldn't be so rainy...
Now, I am drinking "chimarrão" - a typical drink of my homeland, bitter but very tasty for me. It heat me (?). 
Well, that's all for now.
Bye - bye!

The day began cloudy, today... It rained a lot.
I am very tired of this weather. I was born in a place that is very cold in the winter. Now, I live in Floripa - a beautiful island with many beaches. I have been here for 7 months. I hope the rain stop (this did not make sense, so I changed)...
Now, I am drinking "chimarrão" - a typical drink of my homeland, bitter but very tasty for me. It is hot me (did not make sense).
Well, that is it for now.
