Hello there! Today I'm going to show you how to use correctly an exclamation mark (!) yuhu!!
Let's beginning! 

Exclamation mark indicates strong feelings in a sentence, it could be love, fear, etc. (states of humor) It also replaces a period at the end of a sentence, or states of humor.

For example: 

Hey you! I really love you! 

or

To indicate an instruction:

I'm your mom and you don't go to anywhere because I say it!
