Answer 2

According to me this is a very very
important question.The speaker tags are very important.The speaker tags
help you to identify different speakers in case there are different
people are speaking.
It is very easy to write "he said this"
and "she said that" but it is very different when you write about a dialogue.
Speaker tags helps us to write
more than one dialogues
