Long hair

My personal hairdresser here in this town (so called imperial barber or Yu Yong Li Fa Shi in Chinese), who is also one of my best friends here, went to UK for an academic strip, and he won't get back until Nov. 20, the day when I fly back home. That means I wil have to keep my hair and let it grow so wildly that I probably will become unrecognizable at the airport. How terrible, yet please be prepared. : )
