Is it correct to start second paragraph with "Secondly

Could somebody please help?
Thanks.

It's not a question of grammatical correctness; it's a question of style, and writers have different preferences. You can say Firstly,...Secondly,... or First,...Secondly,... or First of all,...Secondly,...

Thanks, InfraBlue.

I would like to know whether we can use "Secondly" when the first paragraph does not start with "First" or "Firstly", as in the following:


Yesterday, I woke up late. I had no time to brush my teeth. I had to go to school in a taxi. Despite that, I reached school late.

Secondly, I was punished by my form teacher. She punished me by making me stay back late after school.
