Should there be any end punctuation after greetings like 'good morning?' Let me clarify a bit. Part of a student's workbook looks like this:
Greeting a person
so, the students are being asked to listen to the given words on a CD. And while they listen, each word appears in front of their eyes as printed text [as shown above].
So, my question is,
1. Should there be a period or an exclamation mark after 'good morning' etc., like there is one after 'hi'?
2. If yes, I'll appreciate if you mention the source of your reference. I could not find it anywhere online!
Thanks a lot.
