I slept in today!

Wow, already 3 o'clock! I guess I am getting kind of lazy in my old age! LOL! :•-)
 
Do you say things like LOL? I just started learning them. There are a couple other ones you can use, like:
 
LOL: Laughing Out Loud!
 
I guess if you are mad at someone you could also say,
 
NLOL! (Not Laughing Out Loud!)
 
You know, to show them that what they said made you upset or mad. 
 
I am LOL, though! Don't worry! I love you!
