Bet ya don't!

Miss is used to imply that you are a single woman, as you should know already. Okay, so what about Ms.?

"Ms.", pronounced as mizz, can be used to imply you are a single woman OR a married woman(That is, regardless of your marital status). When you keep your surname after marriage, you could be addressed as "Ms. whateverisyoursurname".

Now, YOU DO KNOW!

This is the end of the second episode of DO YOU KNOW...? and Jiamin reporting here. I suggest you don't wait to tune in to the next episode as it may take like God-knows-how-long for the next episode to come up:))
