Question

Do you use a comma in this sentence: Mary walked up to me and said Hi

Answer 1

I think no this sentence may be like this

Mary walked up to me and said HI!

Answer 2

no this sentence maybe like this ...

MARY WALKED UP TO ME AND SAID HI

there is not any use of comma ..... uses of comma are as follows ..

Use a comma before any coordinating conjunction (and, but, for, or, nor, so, yet) that links two independent clauses. ...Use a comma after a dependent clause that starts a sentence. ...Use commas to offset appositives from the rest of the sentence

HOPE THIS WILL HELP U.!!!!!!!!
