Rethakul, I'm so glad you're here!
I recommended your book in the 'please help me laugh' thread at
https://www.mobileread.com/forums/showthread.php?t=51165 and I left a review at Feedbooks.
I love this book! I always laugh out loud when I'm reading it. I load it up and read it when I feel like reading something funny. Some chapters I've read several times because they're so funny! Last time I read it, a couple of weeks ago, it was in a single (long) sitting and it made for a very late night.
I've been following your blog for months and I've referred several of my librarian, IT and helpdesk friends to it.
Welcome!
