While watching TV, I suddenly hear Dan snort with laughter at something on his computer. Glancing over, I see that he is reading the blog.

Me: You laughed!
Dan: (confused) What?
Me: You laughed when you read that blog post. You don’t normally laugh when you read them.
Dan: Yes I do.
Me: No you don’t. This is the first time I’ve heard you laugh out loud at one of them.
Dan: I normally laugh at what you have to say. It just tends to happen behind your back.
