Happy Birthday Teach

What a busy week? -- Hey, didn't I say that the last time? Well, it's true. After the weekend wedding extravaganza, it's time to catch up on work. Other than that, I guess it's also the catching up on sleep. I am sure I can say the same for the people involved in the wedding, no? Someone once told me that once you lose sleep, it may take a lifetime to catch up. Let's not hope that it would be the case, despite I have lost track on how many hours I have lost over my undergraduate days. A word to the young folks who dislikes being ordered to bed at 8pm: You'll regret it later.Before I forget, I would also like to wish Sara a happy birthday today.
