The Rule: When two sentences have NO conjunction between them and have parallel grammatical construction, use a semicolon between them.
This question always arises: Could I use a period? My answer is always why would you
pass up the opportunity to use a semicolon? This is one of the absolute semicolon rules.
Use a semicolon here! It belongs here! This is your chance! Be sophisticated!
Happy punctuating!
