We use a full stop at the end of a sentence. Some people also put full stops after abbreviations.
When people speak, they do not always use complete sentences. When we write down their conversation, we put a full stop (.) after each statement even if this is not a sentence:
John: Look at this e-mail.
Peter: Who's it from?
John: Sandra. She's getting married.
Peter: Nice. Are we invited?
In a piece of writing, English sentences must be separated by a full stop (.), question mark (?), exclamation mark (!) or semicolon (;) or joined by a connective like: and, but, so, when, if etc.
Two sentences cannot be separated by a coma unless they are part of a list of three or more statements:
Sandra prepared the pasta, John prepared the sauce for it, and Mary laid the table.
A sentence cannot be separated this way:
We didn't do any shopping. Because the supermarket had already closed.
But
We didn't do any shopping because the supermarket had already closed.
