Not learnt commas
Dog_Father_03
Hello, I have a strong feeling that while I was learning English, all the teachers never said anything about putting commas after the words 'however', 'nevertheless' or 'therefore' when they are at the beginning of the sentence.
Today when I write something in English, all the tools, which help to write, seem to convince me to put the comma in these sentences. Can you guide me what is correct?
e.g.
However, we did not like them.
Therefore, he has decided to make different decision.
With or without comma?
