So I showed Frank my previous post.  He giggled.

As he read it, he giggled and repeated his own lines from the conversations.

And giggled harder.

• Me: You really think you’re funny, don’t you?
• Frank: (giggling) Yeah, I do.  Sadly, I am my own best friend. (giggling some more) ha ha ha – slow children – ha ha ha.  (shaking quietly on his side of the bed)  Ok, enough!

He’s still laughing.
