I don't like rainy days

I don't like rainy days because firstly it's not convenient for people to go out. There will be lots of traffic will be crowded. Secondly, if the rain is too heavy it will lead to a disaster such as a flood. Some people will lose their homes.

A few notes:

-You've used too many commas - it makes your writing sound a little broken up. Try and use fewer commas as this will make your writing flow more smoothly

-You've had some issues with articles, but I know this is difficult for you

-A few issues with plurals, but apart from that it's really good! :)
