Hello!

Hi! Everyone. Hi, everyone!
I decided practicing to practice English here because one of my teachear teachers recommended me this site this site to me, so (No comma needed here) I thought, "Why not?" (Whenever a sentence ends with a quotation containing a punctuation mark, such as a question mark, you do not need a period at the end) 
I hope I can improve my English skills and meet new people with different customs, ideas, etc.

I was exploring the site and I like it.

About my day: I´m sick (I got a cold) because I didn´t sleep with socks 2 two days ago. I´m here with my laptop (I'm assuming "laptop" is the word you wanted) and a tea, and I can´t go outside because outside it is raining.  

:)

Good job!  In English writing, the pronoun "I" is always capitalized.

Welcome to italki, Issa!  I hope you learn many new things here.
