Hey, it's Mr.Wong speaking. Here's a short joke for ya : No English dictionary has been able to adequately explain the difference between "complete" and "finished". Some people say that there is no difference but there is. When you marry the right woman you are complete ! When you marry the wrong woman you are finished ! And if you marry a wife who likes shopping you are COMPLETELY FINISHED ! HAHA, you guys got the joke right ? Alright, let's talk about today's word of the day which had nothing to do with the joke, and that word is "overhear". Check it out !
