Is the sentence below run on or is it something we say to each other
Isn't "Have a great morning/night" a run-on sentence? or can I say "you have a great morning/night"? Or is that just a sentence we say.
Have a great morning / night.
is not something that would usually be written, but more often said. Both your sentences have the same meaning, but when written one might use
Hope you have a good morning / night.
