I have a few grammar tips for you today, folks.
Here's a tip. Never end a sentence with at or to. Examples follow:
"Where are you?" is correct. NOT "Where are you at?" or "Where you at?"
"Where are you going?" is correct. NOT "Where are you going to?"
Where implies location, so nothing else is needed.
Here's another one. "Are you coming?" is sufficient to ask someone if they intend to accompany you. There is no need to add 'with' to the end of the sentence.
Either this or that.
Neither this nor that.
Knowledge is power!
