When you type 'lol', are you actually laughing out loud?
Some people use 'lol' in their posts more often than they use periods.. I really can't imagine an individual being so amused by their own literary stylings.
And whenever someone says 'rofl', this is all I imagine..
Don't get me wrong, I have no problems with someone busting out a 'lol' in response to what someone else has said.. but when people use them as a verbal laugh track within their post, then thats another story.
Anyone who has ever had a conversation with me will atest that yes, I do actually laugh THAT MUCH. The laugh has been described as quite hearty... tee-hee
