About today

Today is Tuesday.
It is cold. I lazily got up. I want to say(delete because we know it is you speaking) It is difficult to get up in the winter. But (it is best not to begin a sentence with a joining word) We (there is only you so use "I" ) have to get up, because I (you cannot use "we" at the beginning of the sentence then switch to "I" ) have a class. It's always busy at the end of every term. (leave a space after periods) We are busy reviewing our lessons and getting ready (or "preparing") to take the exam.
I (am) writing this essay just to practice my English.
