"개인적으로, 저는 몰라요."
Translation:Personally, I do not know.
Something for those living in Korea: if you see a taxi that says 개인 on the top, that means it's a "personal" taxi. In other words, the taxi driver has done his time with a taxi company (10 years, I think) and is now able to have his own taxi. You can know that these drivers have a lot of experience and also that your money will go all to the driver, not his company.
